Hello! I have had this problem, since I went over to Windows 7 x64!
When I want to select multiple files in windows explorer ,as an example I left click and drag a rectangular marquee over the files.
However, if I do this now it always releases the selection randomly
even when I have not relished the button on the mouse.
It happens everywhere,select text. In Firefox,Word,Explorer and other applications it just drops the selection randomly.
This never happens in Win xp or Vista x64.Is there something wrong with a mouse driver
I can say this has been an issue since the beginning of my installation of Windows 7 so I'm pretty sure it has nothing to do with any applications I have installed.
