Error Creating Form Invalid Stream Format

I have an application that I must Inturpret the code as a test. I think it was
written in D5, and I cannot look at the forms Using D4. The error is 'ERROR
CREATING FORM INVALID STREAM FORMAT'. Can anyone give me some insight on this?
I will keep trying in the meantime.
The app. is for displaying images and putting them in the clipboard.

thanx
