>How feasible (aka advisable) is it to go into a screen file and change what class the objects are based on? If it isn't too dangerous, what are some suggestions on accomplishing this.

Not too dangerous, but I would back up first. YOu can also do some redefining in teh Class Browser if you want. And there are a ton of 3rd party tools built to hack VCXs and SCXs automatically. Browse through the FoxTalk stacks if you can't find anything.
