latitude 3440

windows 8.1 64 bit

after switching between user accounts, I can move the cursor around on the screen, but I can't click on anything, not left click or right click

after signing out of the problematic user account and signing back in, the pad works normally

I saw a lot of reports on this problem for linux, but none for windows.

this laptop came with ubuntu installed. I personally installed windows 8.1 64 bit, which is supported, and I installed all the latest drivers.

the dell auto-detect can't find any problems.
