>When a prg is compiled an fpt file is created which holds all the object code. If these files get out of synch then you'll get that error. When a method is closed it is automatically complied and the object code is put in a memo field in a database. I suppose if the memo field that holds the ascii code gets out of synch with the memo field that holds the object code you will get this error message as well.

Thanks for your help Rip. Actually I am working with
Visual Accountmate, So I don't have access to the
exe. Visual Accountmate doesn't provide source for a portion
of the code. The exe calls my custom form, which is
not part of the executable. The form references the class
library. Although the exe has the
class library compiled into it, there is a copy of the
class library in the working directory, and the class library
outside of the exe (I would think) should be available to the
debugger . Especially since the class library has a later save
date than the exe ???

Any thoughts given these additional facts ?

Thanks

David
