I got my copy of Animator Studio on Thursday. Now anytime I enter a windows session where I've used Animator Studio, and I try to exit windows normally, I get an error which seems fairly harmless…THE PROGRAM GROUP FILE HAS BEEN MODIFIED BY ANOTHER PROGRAM OR USER AND WILL BE RELOADED; TYR THE OPERATION AGAIN… Then the system hangs when I try to three-finger out of it the blue screen comes up saying that while I may exit in this fasion, nothing's wrong, at this point I can get back to a solid black screen which is non-responsive to whatever I try Alt-F4 or Alt F X … The error is predictable, repeatable and fatal. If I use Animator Studio I must power-down everything in order to exit. If I don't use Animator Studio life is normal. Any ideas? I'm running a Gateway P5 with 32MB. Matrox MGA Impression Plus at 800×600 16M depth. My permanent swap is set at 20MB. There's a Wacom ArtZ tablet attached, but the problem happens with or without that attached. I'm running Windows for Workgroups 3.11 with a fairly vanilla config and autoexec.
