One trick you could try would be to create a small program file:

* DebugPasta.prg

* Set up an ON KEY LABEL you can press when the spaghetti code "hangs", e.g.:
ON KEY LABEL F10 QUIT
* or maybe you could CANCEL, CLEAR EVENTS, or run your own cleanup code

* Now run the problem code:
DO Pasta WITH ...

* When Pasta "hangs", press F10
