I never install mouseware or Intellimouse. This is my choice to avoid such things.
after exchanging motherboard/processor/ram (and reinstalling OS) my logitech mouseman is acting weird: when i left-click and hold the button for maybe 3 seconds, the click 'lock' and i have to click again to end it. (lock = same as further holding the button. so when i click and hold an icon till 'lock' i can drag it around till i click again...).
i use win xp pro SP1, newest mouseware and i have a 2nd pc with same OS/mouseware and there i dont have this problem.
mouseware does not provide an option to disable this 'feature', and i dont find anything in the sindows settings.
its really annoying to work with this. any idea welcome!
thx!
