- LoopNum1 "not available": LoopNum1 just counts the number of loop cycles. So it is 0 until the code inside the loop was executed at least once. Check how your loop behaves in the FIRSTRUN.

- Z-systems crash: Make sure that all executables, with .x extension, run on the same Zorro version where they were compiled. If the versions do not match, it can crash.

- Zorro S: The Zorro S license works with all versions. A beta version is not different to a release version, only difference is that it was not tested a long time.


If that does not help, please post again with some details about the problem.
