Tom,

After I removed the timer, I can no longer reproduce the problem. It doesn't yet mean, it was indeed timer related and it is indeed gone, but I was able to reproduce it before and I'm unable now.

I guess, I would have to live without timer and tooltips for this particular form for the time being.

Thanks a lot for your suggestion.
