I too am seeing this same problem with Ubuntu 9.04 and my Microsoft Intellimouse Explorer 4.0
If the mouse is moving, the mouse scroll wheel does not work. This problem did not exist when I was on 8.04. I upgraded to 8.10, just so I could upgrade to 9.04, so I didn't try it under 8.10. Another oddity, is that when the mouse wheel does work, the scrolling seems rather slow (in Firefox). -- Intellimouse Explorer 4 wheel wont scroll when mouse cursor is moving https://bugs.launchpad.net/bugs/348010 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
