Thanks for the replies, all.
However, I would still like to know the answer to my original question: given that it's so easy for settings to change, how can one revert one's entire environment/hotkeys, etc. to the original default settings?
I can't believe there isn't a way...
TIA.
How do I reset all default settings for cad 2007 3D (interface, system variables, etc.?
Damn thing decided not to use standard file dialog bioxes any more... bloody frustrating.
TIA
