>I have accidently created an object (in fact a form based on my own form class)using the correct class but from the wrong class library (actually from a backup of the class on another disk). Can I edit the form class so it uses the correct class library?
Yes.
1) Important! Make a backup of your form.
2) USE MyForm.scx
3) BROWSE
