I currently have a problem subclassing a form (itself subclassed from a baseform).

The symptoms are curious. When trying to add a new class into the VFP5 project browser :
1 - the parent form class refuses to be subclassed (leaving VFP in
an error state),
2 - VFP sends error message "expression evaluated to an illegal
value (error 46)" which absoluted unrelated to the pb itself.

A a cure i have tried the following :
- recreate the form class,
- change the names of controls and the form itself (in case names
would contain VFP reserved words),
- open VCX, delete object code and pack it.

Still unsuccessful. I can subclass all objects except this one.

Any idea
