AutoCAD 2010 (and now 2012 because IT migrated settings instead of fresh install - another post for another time), the tool palettes inside the BE, the ones that should have the Parameters, Actions, etc. are empty, except for a little message at the top asking me if I want to know how to customize tool palettes. Um, no thanks, I know how to do that. What I need is to get the ones that are actually built in to AutoCAD to actually show the content.
All I can do currently is try to decipher which icons at the top of the block editor mean parameters, actions, etc. (could they BE any more cryptic?) and enter the options at the command line.
I have no idea why they disappeared in the first place. One day they just weren't there.
