I was looking really for some way of taking the power off of the ps2 mouse port in software, then putting it back on. It appears that when this A4tech scrolltech mouse's pointer locks up, the only option is to take the power away from the mouse, then re-connect it, which is tantamount to pulling the ps2 plug, then putting it back in. If there's no way of totally disabling the ps2 mouse port, then re-enabling it, using software and the keyboard, then it's no problem. it's only an intermittant problem, and even though I may lose some stuff on open consoles when having to do a shutdown, it's no big deal. I just thought that someone might have a quick fix. I have asked this question before, but have never found a fix for it. Thanks for the replies.
