2. Touch the DS icon in the bottom middle of the screen.
3. Press the far right yellow icon.You will then be taken to the calibrate screen.
4. Touch the small red squares on the screen as they appear.
5. Press Confirm amd exit menu.

Sounds like you should try recaliberating the touch screen. Calibration must be done with a stylus. Please note: Using a unlicsensed screen protector can lower the sensitivity of the screen, making calibration difficult. If the problem you are encountering started happening after installing a screen protector, this may be the cause of the problem. Remove all games from the Nintendo DS. Turn the system on by pressing the POWER button. Press the A Button when the "Touch the Touch Screen to continue" message appears. When the main menu appears, use the Control Pad to to place the cursor over the Settings Menu Panel at the bottom of the screen, and press the A Button. should look like this :

Use the stylus, and tap the red square that appears on the screen. Do this each time the square moves. You must touch the red square precisely at each of the three positions, otherwise the test will continue to re-start If the touch screen is not responding properly, hold the Nintendo DS at an angle so that you can see where the edges of the Touch Screen meet the housing of the system. Look around the entire edge of the Touch Screen for any foreign material (such as crumbs, etc.) that may be wedged in between the Touch Screen and the housing of the DS. Foreign material in this area can cause the Touch Screen to work incorrectly. When complete, four squares will appear, allowing users to test the touch screen sensitivity. (Testing is optional.) Tap the "Confirm" button in the lower-right corner. Wait for the the confirmation message to disappear, then tap "Quit," then "Yes" to exit. The unit will shut down automatically to save the settings. hope this helps

If you would like to calibrate your screen...
Turn the DS on without a DS card inserted (or with auto mode turned off).
Then touch the DS icon in the bottom middle of the screen.
Press the far right yellow icon, with a crosshair in it.
You will then be taken to the calibrate screen.
Touch the small red squares on the screen as they appear.

Press confirm, exit menu.

Turn the ds on without a game in it and go to the settings icon (looks like a tiny ds) on the bottom middle of the screen then go to the far right yellow icon and it will re-calibrate the touch screen and let you know if calibration was a success.

Might need to re-calibrate your screen. From Nintendo's site.

1 Remove all games from the DS.

2 Turn the system on.

3 Press the A Button when the "Touch the Touch Screen to continue" message appears.

4 When the main menu appears, use the Control Pad to to place the cursor over the Settings Menu Panel at the bottom of the screen, and press the A Button.

5 Use the Control Pad to place the cursor over the orange icon that looks like crosshairs (the right-most icon), and press the A Button.

6 Use the stylus, and tap the red square that appears on the screen. Do this each time the square moves.

* You must touch the red square precisely at each of the three positions, otherwise the test will continue to re-start.
* If the above steps did not help, there is a problem with the system and it will need to be repaired.

I think your touchscreen must not be calibrated correctly. Turn on your ds without a game and go to the little tiny ds a the bottom. Then click on the yellow orangish icon and it will start calibration. Just touch the marks with the target things to calibrate it.

Do you mean the touch screen?
Have you tried the alignment procedure?

Remove any cartridges and go into the setup by pressing the small icon at the bottom center of the screen when you first turn on the ds.
Press the yellow square (alignment) and follow the instructions.

When you turn on the ds, go into settings (the center icon at the bottom), the press the yellow icon. I assume you got to that part.
Now you have to tap the calibration points; as you touch them, they should move to the next point (three altogether). Does that happen?
Next, you should be able to test it at four points. They will turn blue when you touch them. Does that happen?
If there is no response when you do this, your digitizer may be faulty.
The DS will reset to factory if you remove the battery. You need a small phillips screwdriver for that, on the bottom of the DS.
