Can a macro corrupt? Exact same code works in other macro.

[frank]

I have a macro that all of a sudden (after running it over and over during development of it) just wouldn't "run" my app.
Finally I stripped out everything down to the one line:

run "C:\Program Files\SAP\SAP Business One\SAP Business One.exe" "" "" "" 0 "SAP"

No response, no error.

I pasted the line into a new macro and it worked.

I pasted the rest of the code into the new one and it all worked.

I deleted the old one, renamed the new one and I'm back to working.

Has anyone experienced this?
