I have Windows 7 with a USB optical mouse.

Sometimes my mouse starts behaving abnormally. When I move the cursor everything starts highlighting. Right and left clicking does not work all the time.

I am unable to write properly. Whenever I start writing text it starts highlighting and the cursor moves backwards automatically.

I always have to restart the computer and then it works okay. The problem happens every few months. Any ideas?

Have you tried using a different mouse to see if you get the same result? It could be drivers, the mouse failing due to wear and tear over time, etc. – PeanutsMonkey Oct 12 '11 at 6:54

Are you using a laptop and are you accidentally resting your hand on the trackpad under the keyboard? Far too often have I accidentally "clicked" the trackpad with the palm of my hand.
