Ok still strange, however I have now registered and waiting for the licens.

I have a feeling that it is the small red "TRichView unregistred" that might

cause my problem. I have a function in my mainform that runs frequently and

loop all forms in the application in order to update several status. I dont

know if this "TRichView unregistred" is a form in the application collection

but I hope so. Otherwise I will contact you again. BTW I contact you anyway,

can be good to know for the future.
