Left mouse button keeps clicking

Key could be stuck on keyboard. Try banging on all the keys (not hard enough to break - just hard enough to unstick). Try a different keyboard.

go to mouse's options.and change double click speed.it can solve.

Similar problem which I resolved today.
I have a hp wireless mouse model no. 5189URF. I bought this in hp online in April 2009. It needs 2 x AA Alkaline batteries.
Steps I did to resolve.
1. Removed battery cover.
2. Removed batteries below which 2 screws exist.
3. Remove 2 screws and remove the top casing of mouse.
4. You can see 2 very small square push button corresponding to left and right clicks in mouse.
5. try to press the left button and make sure its free. The issue seem to be that this button becomes rusty internally and lost contact. Therefore clicks are not recognized. You may need to press it repeatedly and also with a slight thrust circumferentially.
6. You can test your mouse in WIndows Help & support option linked with HP hardware diagnostics tool.

I have the same problem. I posted on HP forum but did not get any help. I contacted HP technical support. They sent me a new mouse but it behaves the same way.

mcdevito75 here, Sounds like the mouse itself is faulty, if the right button when depressed returns to position and you hear the familiar click, and you don"t hear that from the left button, then the mouse itself is faulty, ask Dell to send another mouse, it should be on warranttee with your new computer.

Step 2: With the left mouse button, click on 'Control Panel'.

Step 3: With the left mouse button, click on 'Network and Internet Connections' (Network Connections, if in Classic View).

Step 7: With the left mouse button, click on the 'Wireless Networks' tab.

Step 8: With the left mouse button, click on the name of the wireless network, under 'Preferred networks', that you want to automatically connect to.

Step 9: With the left mouse button, click on the 'Properties' button.

Step 10: With the left mouse button, click on the 'Connection' tab.

Step 11: Ensure there is a checkmark in the checkbox, next to'Connect when this network is in range'.

Step 12: With the left mouse button, click on the 'OK' button.

Step 13: With the left mouse button, click on the 'Advanced' button.

Step 14: With the left mouse button, click to select 'Access point (infrastructure) networks only ' (This will help prevent your connection from bouncing around from one network to another).

Step 15: With the left mouse button, click on the 'Close' button.

Step 16: With the left mouse button, click on the 'OK' button.

you should change your mouse cuz only left mouse have this physicall problem due to extra pressure or hard clicks on it.mouse is sensitive device so repair is not better option.just change it.

check the bottom of keyboard and wireless pickup device..lights should be steady on..if not, reset with buttons..also, check battery charge, by replacing battery..also re seat the wireless pickup into another usb port.

Normal 0 Turn the mouse over and find the small rest/connect button on the bottom of the mouse and press it to Reset/Connect the mouse to the receiver and work properly.
If not, try pressing the receiver button and then press the mouse. This should be done whenever you change batteries or glitch.
Hope this helps you. Bud

Normal 0 Go to Control Panel and click on the Mouse icon. Then the mouse properties will appear showing the mouse buttons. Put the pointer on the left button and then go to the drop down and make sure the buttoon is set properly.
Hope this helps. Bud
