Certain dialogue boxes won't pop up, like bhatch, eattedit, or some of the C3D boxes like when trying to edit AEC point display items. This is the second time this has occured. the first time fixed itself and I don't know why? when envoked AC acts like the box is there but I don't see it. If I do an ESC the the commad cancels and put me back at command prompt. It's driveing me crazy!!!!!
