Try going into the Touchpad settings to make sure you have the Defaults set. Click Start/Control Panel and look for Mouse or Touchpad.

Reinstall the touchpad drivers.

Get online and got to www.google.com In the google search box type: "Samsung Support" (without the quotes and put your manufacturer name before Support). Look for downloads and drivers. Enter your model number and operating system when requested. Download and install the drivers.

Maybe your touchpad mouse has been hijacked by a virus or infection.
Get into safe mode and see how it functions.

Turn off the computer, then hit the power button to turn it back on and immediately start hitting the F8 key repeatedly until you see SAFE MODE. Take the Safe Mode option and let it boot up. Safe Mode will look different to you, the screen will be darker and the icons bigger, this is normal.
If the cursor behaves in Safe Mode repeat the process to boot into safe mode, but this time select Safe Mode With Networking (this will give you internet connectivity). When it boots up, open your internet browser and download and install MalwareBytes.


Go to www.google.com and in the search box type: "Download cnet Malwarebytes" (without the quotes). Download and install malwarebytes from the sites download.cnet/malwarebytes. When the site opens up click on the Green Download button on the left. Do not click the Red Download button, that's junk. When it finishes installing the Gui Interface will open up with an offer to Accept a Trial Version or Decline. CLICK DECLINE you want the totally free version. Run a QUICK SCAN. As it scans, if it finds infections the number will be in red. When it finishes scanning, click SHOW RESULTS. A notepad text document will open up showing you the results. You can close the text document and go back to the Gui Interface where you will click REMOVE SELECTED RESULTS. The objects will already be selected for you. When it finishes removing the objects click ok and it will sometimes reboot your machine.

Cursor jumping around while typing text

You wouldn't have some live insect in your keyboard have you? I've seen Microwaves do strange stuff when infested with some tiny insects BUT I doubt it's the case with your machine. I am trying to recall a Keyboard key that I sometimes accidentally press when trying to create a document using Word, etc which does the same or similar to what you've described. It pees me of as I don't know which button I hit, it is one of the main reasons I avoid Word, Outlook, etc. Please let us know if solved, cheers.

When typing, cursor jumps backward several spaces

Sounds like your mousepad is ghosting. This means it thinks you're tapping the mousepad as you type, which will make it type exactly where you nlast moved the curser to. First, try cleaning the pad thoroughly with a damp tissue, and dry it well... if that doesn't solve it, you could try adjusting the mousepad sensitivity controls on the control panel. Hope that helps.

My Electronic crossword puzzles by RadioShack comes on but will not do anything. I just put in new batteries. I do not have my manual.

Adjusting The Display

To increase or decrease the display's contrast so it is easier to read,
hold down FUNCTION, then press /\ or \/ on the cursor pad.

Playing The Game

1. Press ON/OFF to turn on the game.

If you have not worked a puzzle since installing or replacing the
batteries, CROSSWORD MASTER appears. Otherwise, the display is as it
was when the game was turned off.

2. To start a new puzzle at any time, press FUNCTION and 1 (I), 2 (O), or
3 (P) at the same time. 1 is for beginner-type games, and 2 and 3
increase in difficulty. NEW GAME LEVEL 1, 2, OR 3 Y/N appears.

3. Press Y to start a new puzzle. A crossword grid with flashing cursor
appears (O).

Otherwise, press N. The display appears as it was when you pressed
FUNCTION and 1, 2, or 3.

4. Press (or hold down) /\, \/, <, or > on the cursor pad to move the
cursor around the puzzle.

5. With the flashing cursor in the desired location, press ? to see the
clue(s) for the word(s) in that location.

Any letters you already entered appear, along with a dash for each
missing letter. The number of letters appears in parentheses - for
example, (5) for a solution with 5 letters. If the solution includes
more than one word, the number of letters for each word appears in the
format - for example, (5, 3, 4) for a solution with three words.

If the flashing cursor appears at the junction of two words (across
and down), both clues appear, across first, then down.

6. Press ? again to return to the crossword display, then use the letter
keys to type your answer.

If the flashing cursor was at the junction of two words and you enter
the first letter of your answer, two small arrows appear in the
adjacent across and down squares. Before typing the rest of your
answer, press > or \/ (across or down) on the cursor pad to indicate
which word you are entering.

Press /\ on the keyboard to erase the letter just above, and < to
erase the letter to the left of, the flashing cursor.

To erase a word, hold down FUNCTION and press WORD DELETE (Z).

To spell check the puzzle at any time, hold down FUNCTION and press
SPELL (T). The [+] symbol indicates the location of each incorrect
letter.

When you complete a crossword correctly, GAME COMPLETED appears.

7. Press ON/OFF to turn off the game. The current puzzle is saved.

Cursor not moving when I type

try other programs to see if it works fine there. it could be an issue with the web browser. if you are using Internet Explorer, try using Mozilla FireFox. It is more secure and really easy to use. goto getfirefox.com to get it.
