Events are reported as fast as the kernel mouse driver can report them. This is typically faster than human reaction time. On a bog-standard PS/2 mouse using the IMPS/2 protocol and the standard X settings, I get a typical X timestamp difference of 80-90 milliseconds between button 1 press and button 1 release when I'm clicking as fast as I can. There may be some other differences depending on how fast the machine is and how heavily loaded it is. > The problem I have is that when I click on a position in an editor and > then move the mouse I often get some unwanted selected text (i.e. it > is behaving as if I were holding down the mouse button because I'm > moving the mouse quicker than the up event is being registered) > It would speed up work if I could move the mouse more quickly after a > click. Lay off the caffeine? I've never had this problem, but then I think "more haste = less speed" when it comes to writing/editing. Or better yet, edit text in such a way that you don't need to use the mouse at all. (There are 2 text editors, vim and emacs, neither one requires the mouse, and both can do things that are very difficult or totally impossible in other text editors.) -- Matt G|There is no Darkness in Eternity/But only Light too dim for us to see Brainbench MVP for Linux Admin / mail: TRAP + SPAN don't belong http://www.brainbench.com / "He is a rhythmic movement of the -----------------------------/ penguins, is Tux." --MegaHAL
