I'm having a problem with the configurations resetting in Solidworks 2008 (64 bit). I realize that the buttons re-map according to whether your in Part, Assembly or Drawing modes, but it doesn't seem like there's any logical way as to when it changes back to the defaults. Can anyone provide any insight? The only consistency I have is to save multiple configurations, and try to keep overwriting what I'm currently using with a master config I never use. I've searched the forum a few times and can't find anything.
Here's the system specs:
Windows Vista 64 (Business?)
Solidworks 2008 SP4 (64 bit)
3dConnexion release 3.6.8, Driver 6.6.1
Spacemouse +
Thanks in advance for any help

I can design anything you can afford. Oh wait, you want it to work???
