Verrrry good call...

Actually, you are both right: downward compat is not always garantueed. This is why I store a versionnumber in the tokenized scripts. If a new version of KiXtart needs to make some change in the tokenstream, I update the versionnumber and the new version of KiXtart will only run with newly tokenized scripts.

However, I didn't change anything the tokenstream in 4.61 (or at least, I didn't intend to...), so 4.61 should really run 4.60 scripts just fine.

Turns out I broke something...

Fixed in the next build (which I hope to send out asap).

Thanks for the test and report!
