the threads don't terminate. If I do the same thing in a Form (I create the non-visible object TJvThread in a form, set the properties and so on) it does work without any problem.

Why do I want to create TJvThread manually? I have a component where it should working on. But it doesn't. Same problem as in this example.

Ok I found the problem. If I put a "Application.ProcessMessages;" in the while loop (while not (FThread.Count = 0) do), it does work.

Also the correct while loop is =
while not (FThread.Count = 0) do

I think we can close this bug
