Microsoft Intellipoint mouse software is not compatible with Solidworks!
After scrutinizing the driver options, phone conversations with Microsoft techs, a replacement mouse, and searching various forums, I have to conclude that the Microsoft Intellipoint mouse software is not compatible with Solidworks.
So if you were thinking of buying a Microsoft mouse to use with Solidworks - Don't.
Problem: Middle button (wheel button) does not rotate the model view reliably
Microsoft Intellipoint 8.2
Windows 7 Professional, 64 bit
Microsoft Comfort Mouse 4500
Microsoft Sidewinder X3 Mouse
If someone has some magic workaround for this issue, please post it here.
During my investigation, I noticed that the middle button works correctly in SW, if the Intellipoint software is uninstalled. But then you lose the use of the extra side-buttons, which as you know are a huge advantage.
I'm going to hound Microsoft about this a bit, it's not like Solidworks is some obscure application with a tiny user base...
