Sometimes when I try to open up new tabs inside a window by clicking the mouse wheel the computer will just show 'connecting' in the tab header and wont do anything at all. After I close it it does the same thing again working its way down until I can have only one tab open, like say it freezes on the 7th tab and I close the 7th and the 6th it will then freeze when i try to open a new 6th etc etc. Also when this happens the right mouse button stops working completely, it wont work on the desktop or anywhere else other than games where it works fine.
The problem generally only occurs when I try to open more than say 6 tabs and even then doesnt happen everytime, but it does happen frequently.
The only thing that fixes it is if I log off and log back on, then everythings fine.
My comp is an HP m7780n w/ vista and my mouse is a logitech g5.
