Hi I have noticed that this happens each time I try to create any interface object which is not in the main thread, e.g. in a separate SCOOP process. I had that problem with one widget and moved that to the main thread. Then I got the same problem with the next widget. I assumed that it should be possible to have some parts of the UI in a seperate process, since I can use extend which takes a seperate object, or am I missing something? Regards Anders
