>You can't modify a class that's currently instantiated - you have to release all objects in memory that use that class before you can change the class.

Hi Ed

Ok but if i don't make a instant
i only use the command {Modify class myClass of myClasslib.vcx}
this is possible that foxpro make a instant to modify the class but don't release it when i close the modify form ???

it's also happen when a class in the classlibrary(A) is a child of a other class in a other classlibrary(B). right after the modify command on the classlibrary(A) i can't delete the classlibrary of the parent(B) it also give me "FILE IS IN USE"

I know that {Clear All} command release the possible reference to the classlibrary but it also cleared all memory variable. That's the problem.
