Comment 4 for bug 773533

I have the same problem after installing 11.04. There are intermittent dead spots where scrolling with the mouse wheel will not work for a few seconds, and then it will work OK. Sometimes the links will not work, and then a few seconds they will be fine. Even on this page it froze a few times. I have only noticed it on browsers (Chrome, Opera, etc) but I suspect it may happen elsewhere. Very annoying. Everything worked fine under 10.10. Doesn't matter whether I use Unity or the classic gnome desktop, still have the same problem. I have an HP USB mouse.
