I have imaged a Dell Optiplex 755 with Windows 7 32-bit, at random, the mouse buttons swap themselves over. This is rectified when the user logs off and logs back on. The reg entry for the mouse is NOT changing from 0 to 1 so it's not registry related. Didn't have this problem with Windows Vista previously.
I have updated the chipset to the latest version, released in 2010. It's not happening on a Dell 7010 with the same image.
Multiple users are experiencing this and I have not found a solution yet.
Any ideas folks?
