- That was fast in more than one area. :-)

- Cool.

- This is very important for people who is runing it under a multitasking
- eviorment as you get alot of redraws if you switch program and also
- for the dialogs from GEM-DEU it self.

- Ofcourse.

- The rest sounds just great. I guess you will have to wait until you get back from
- the states before you could work more on it. You would probably have your AB040
- bu then. They are still dragging their feets on getting the 33MHz CPU shipped so
- I doubt that we will get them this week. :-((

- I will take a look at it.
