I've had an ongoing issue with my mouse when using SketchUp. When I click the wheel button to use the Orbit feature, I get nothing. (It should behave as described here.) I have to either select the Orbit icon in the toolbar or press the O key to get this functionality. Once I'm in Orbit mode, the left mouse button works as expected. Then when done, I press the Space bar (or select another tool from the toolbar) to do other operations. This has been going on for a long time (about 2 years or more) and the problem has spanned two different computers and mice. My current machine is a year-old HP laptop running Windows 7 and a Logitech M305 mouse with the standard drivers it came with, so it's not like I'm using oddball hardware or software.
Any ideas for a fix? Has anyone else seen this problem?
