I keep getting the above error with a class that I have. 'Clear all' releases whatever is causing the problem, but I need to fix the class.

I have a class called vwbBase. It's a container with a couple labels in it. I subclassed it and created two more classes vwbClient and vwbBillTo.

I put vwbBase on a form and run the form, close the form, try to edit vwbBase and it works fine.

I put vwbClient on a form do, the above, it works fine. I put 2 instances of vwbCleint and it still works fine.

I put vwbBillTo on a form, do the above, it works fine. I put 2 instances of vwbBillTo and it still works fine.

But, If I put 1 vwbClient and 1 vwbBillTo on the same form, run it, close it, and try to edit any of the those classes I get "Cannot modify a class that is in use"??????

I ran DF's ObjRef after running the form, it didn't find anything.

I have checked the classes and everthing is local (with the exception of a couple public properties that only store strings). I don't store any obj references anywhere in the classes. I've recreated vwbBase from scratch. Tested with different forms. Tested with a plain VFP base form. I added a release method to the contain and put release this in it. In the destory event I put this.release. Nothing I've done has solved the problem.

Does anybody have any ideas? I can't figure it out.
