Joel_Mulig,
Thank you for sharing your code.
Some suggestions:
1. Refactor it to use the Event structure which was either not yet available or very new in 2003.
2. Refactor it to use a state machine architecture.
3. Eliminate local variables.
4. Eliminate sequence structures.
5. Eliminate Formula Nodes.
6. Add Dcoumentation to the VI Properties.
7. Create custom icon.
8. Enlarge the panel and buttons so the text is more legible. Screens tend to be much larger than they were 11 years ago.
