Mouse Pointer issues

Ill get right to it...

Hardware Installed New ram, is the only thing I have done, and the problem started last week, about a week after I put the ram in.

Software: The new windows 7 updates, other then that nothing

All of a sudden my mouse only Left clicks on things it wants to. I can select icons on the desktop, but I cant click the start menu or the "X" to close a window, nor drag windows. Sometimes it can be the other way.

This is very Irritating, I just restart and hope it works the next time.

I can confirm this issue, since I am using a laptop and both external and touchpad double tap, and clicker have the same issue.

First I'd try the Sys. File Check. Info here if needed: SFC /SCANNOW Command - System File Checker

Since you have not installed any software other than updates, you could try a system restore to a point before this started. You'll probably have to reinstall the updates. Do that one at a time in case one of the updates proves to be the problem.
