We are running an add-on in SBO 2005A for several years with many SAP customers.
When tried to upgrade to SAP 2007A the add-on keeps crashing always when a form is closed.
To upgrade it all we did is changed the refenerence to the two interoparability dlls and recompiled the add-on.
It installed fine but on any form when a Cancel button is pressed the add-on fails.
Thanks for your help.
