Hi Christian,
>I've a really bad problem, since I created a report, which should be called from a certain form: When I trie to modify this form, the Computer is freezing so badly, that a restart is necessary.
This sounds me like a corrupt file. If it's the SCX that causes the computer to freeze, I'd assume that something in your SCX is wrong. Do you have a backup?
