FORM freezes

A form freezes and never executes the first line in "WHEN-NEW-FORM-INSTANCE". It worked until recently. I have taken the items/tab-screen that I have recently added, but I still get the same results. The JAVA console also freezes and the only thing I can do is kill the IE (9) screen.I can't run it in debug-mode, since it never seems to execute the first line in "WHEN-NEW-FORM-INSTANCE". I can't figure out what my next step is, except start NEW (not preferred solution, unless only solution possible).
