Re: Thread changes?

Hi Brendan,

After working a few hours on the problem, I found the bug if it's a bug and
FTC isn't the source of the problem. However, the problem appeared for the
first time with b15pv17. The problem was the number of controls on the
window. There was too many controls on the window. I don't know the reason.
I can't find an explanation. Nevertheless there was a thread problem with
b15pv17 that was solved in b15pv18. I confirm it has been fixed.
