Hey, just came across an annoying thing. I've got a KVM switch here which may or may not have to do with it, but... When I'm in a browser, so far IE or Avant, the scroll wheel more often then not, refreshes a page, or goes back or forward, instead of just scrolling. Like for example if a long page is displayed and I use the scroll wheel on the mouse, it will start to scroll and then refresh the page. If I just roll the wheel like there's no tomorrow, it refreshes continually. If I scroll up, it will start going back a page in the browser. On one of the two PCs, scroll up and down will go back and forward in the browser, which is extremely annoying. Obviously there are no settings for this in the browsers, or in control panel. And I've since used 3 mice. And there is no special mouse software or utilities installed. I would guess it's the KVM, BUT, I've been using it for a long time and never had this issue. And also I always have other PCs plugged in to the KVM in the other two ports, and they never do it. So just these two machines, one XP and the other 2000 Pro, have this wacked scroll whell phenomenon. I haven't spent loads of time troubleshooting it, but I thought I'd post a thread about it, in case someone else has had this issue, or someone else has this issue in the future and stubles across this. Any ideas? Thanks.
