Microsoft Intellipoint 5.1 for Mac Shows No Mouse

I downloaded Microsoft’s Intellipoint 5.1 Mouse application today. While it installed without a hitch on my Quicksilver running Jaguar, I found that on my Panther powered MDD PowerMac, the preference pane showed the wrong mouse. In fact, what it showed me was a regular Microsoft two button mouse icon with a big red ?x? through it. I uninstalled the application completely and reinstalled it but got the same result.

The MDD is running an older MS mouse, an Intellimouse Explorer 3.0 while the Quicksilver is actually running a newer Intellimouse Explorer 4.0.

I solved the problem by uninstalling 5.1 and reinstalling Intellipoint 5.0. The preference pane now shows the correct mouse.

This is the first time I’ve had this problem with an Intellimouse upgrade. But it just goes to show you that QA is a problem not only for Apple but for Microsoft...which is why I'm going to wait awhile before taking my XP machine to Service Pack 2.
