Windows 7: Window focus getting lost every few seconds

Since past 2-3 weeks I have noticed an issue that bugs me too much. The focus on a window keeps getting lost automatically.

Lets say I am reading a page or writing in a textbox (like this one), the current focus would automatically get lost and again need to click somewhere in the program. I may be scrolling down using scroll bar of mouse or arrow keys of keyboard or my cursor is being pointed somewhere in a textbox. Because of this issue, I again have to click manually a program.



I tried googling but could not find a suitable solution or root cause of the issue. Maybe there is a program that gets activated automatically and focus shifts to that hidden program - however i could not find one.

Would appreciate if someone could help me out on this.

Having the same problem. Possible solutions are being discussed over here: Window focus is stolen but doesn't go anywhere

Good job, Yannick, that will save us from running around writing the same posts over and over again
