Summary

Old Project won't run

Type             : Bug
Priority         : Medium
Gambas version   : Unknown
Product          : Unknown


Description
-----------

When I attempt to open an old (small) project that I cobbled together under gambas2 (but I'm sure still worked in earlier versions of gambas3), I get the following error message:

CComponent.Load.626

'UserControl' class is missing in gb.form component exported classes.


Any clues gratefully received.
