Strange things happen: nothing opened on VFP, the DISPLAY MEMORY command shows nothing behind all vfp system memvars, and, when I try to execute the command: REMOVE CLASS x from y.vcx I receive the message: 'Visual class X is in use by MODIFY CLASS'.
The commands CLEAR CLASS or CLEAR CLASSLIB don't work. If I execute them, and try again the REMOVE CLASS, I receive the same error.

The only thing that works is issue CLEAR ALL, but I can't do that from within an .APP that receives the same message when executing the command ADD CLASS.

I don't know how to workaround that. Please help me.
