Posted this in several Windows/Tech forums but have been unable to resolve so far. If anyone here can help, I'd be most grateful.
Been having a weird problem with the mouse for a few weeks. Happens several times a day.
When I go into any application where you (use the mouse) to select one item, several random items are selected all at the same time. In Thunderbird, for example, selecting one folder, selects 2 or 3. In explorer, selecting one item highlights many more; and when I click on Firefox (to re-open the window) it kicks off another instance of the program; clicking on a pinned tab (in Firefox), doesn't open it but protects/locks it instead.
Closing & restarting the progs fix it, but it affects every running program, so I usually end up logging off and back on.
Swapped the mouse & tried a different USB port. It can't be the keyboard (I hope) because logging off/on rebooting always solves the problem until the next time.
Any ideas as to what's causing this ??
