can't right click after hibernation

Archived from groups: microsoft.public.windowsxp.help_and_support (More info?)

I have a Gateway laptop with XP Home Edition. I recently bought a new
mouse, a Kensington Pocket Mouse LE model# K72218. I downloaded and
installed the software from their website. I had lots of problems after
that. I tried to uninstall the software, it wouldn't uninstall. I
contacted their tech support by phone, which didn't help me at all. So I
tried to get rid of it by doing a system restore back to before I downloaded
the software. But that lost a different program I downloaded after that. I
went back and forth trying to find a spot where the computer worked and I
had the other software I wanted. The last time I tried I couldn't do a
restore, the computer just froze up, and there was a message about virtual
memory. After several calls to Kensingtion tech supp I did get the software
off my computer and everything seems to be working now EXCEPT after I wake
up the computer after hibernation, I can't right click. To be able to use
right click, I have to restart the computer and then the right click works.
Kensington finally told me that the mouse was probably defective and sent me
a new one. It just arrived. I put the computer into hibernation to test it
out and the new mouse is the same as the first one--it will not right click.
I tried my old mouse and I can right click with that.
Any ideas on how to solve this problem??
Thank you for any help you can give me.
