>After running and closing form (defined in VCX) I am not able to edit some or all of classes contained in that form. Sometimes even for the form I get same message. There are no instances of those object in memory (well at least shown in debugger or with DISPLAY MEMO), but SYS(1016) shows very high memory useage for users objects!!! Is this happening to others and how to avoid CLEAR ALL every time after testing forms?

What is probably happening is that the class library that contains your custom control classes is not releasing when you destroy the form. Issuing a SET CLASSLIB TO will close all class libraries. If you know you want to leave some class libraries open, just remove the ones you do not want open with the RELEASE CLASSLIB command.

I have discovered that if I want to edit some of basic classes first I have to "edit" one that holds one of those objects. This seams to force VFox to release some of definitions. Anyway, none of those things helps fully and CLEAR ALL is
only solution if it doesn't crash.

Thanks to all on your suggestions.
