I have an OmniPlan trial installed, and it has recently decided it wants to open all of my Omni documents opened from the Finder: OmniOutliner and OmniGraffle files that I double click in the finder end up opening in OmniPlan. Looking at "get info" in the finder shows that OmniPlan is registered as the default handler for these files. If I change it to the correct application and attempt to apply it to all files, it switches itself back to OmniPlan. Open With still works if I manually select the correct application. What is going on?

It appears to have fixed itself. Odd.

Heh, well, if it happens to someone else, maybe they'll find the answer. :-)

It sounds like a part of the OS called "Launch Services" has gotten confused.

The specific steps to use to reset Launch Services depend on what version of Mac OS X you have installed, but this google search should get you started...
