Well... maybe we shouldn't blame the Dell PC just yet!!
Did you get that message when selecting, copying a Case Statement and pasting it into a brand new vi? Then trying to run the vi from which it originated before saving or changing the new one? (although you may have changed the original one...)
If you can't remember, try these steps:
1. Open an existing vi with a Case Statement.
2. Select the Case Statement and copy it into a new vi.
3. Make a change to the original vi. Try within the Case Statement.
4. Don't save yet..
5. Run the original vi, while keeping the new one opened and unsaved.
6. Let us know if the insane message popped up!!
:O)
