Could you shed any light on WHY this is happening??
First: this is an OS issue. It's not a Max issue.
You have multiple applications on your hard disk claiming to 'own' files ending with the suffix .maxpat. The OS has to decide which one to use when you open a document from the Finder. The complete strategy is complex, but one of the first rules of thumb is that the application with the most recent create/mod date trumps.
When you tell the OS that you want it to use a different app, the OS shrugs its shoulders and sez 'awright, do it that way."
