I have one user that is having an odd issue, still looking into it, but thought I would throw it out here as well, difficult to dig through all knowledge base info.
Anyway, when he selects the "View Orientation' of a part or assembly, selects the view he wants, it changes the light settings, then from within the lights area tab, he resets properly and all is well.
This does not happen all of the time, if fact it stopped doing it when I went to his room to check it out. I will probably update video card, but doubt it's that, and he isn't proficient enough to set these on his own
Thanks for any help you can be,
