If your problem is reproducible, that's good news :-)

Mmm, I'd say that with so little clues it is going to be difficult to
help you. Please, whenever you submmit a problem to a list, try to
isolate the issue as much as you can and try to describe it with detail.
Ultimately, providing a small piece of code reproducing your problem is
the best thing so as to allow other people helping you.

Cheers,
