All of a sudden, SS 64 is broken. It starts, and I can load a file into the MultiTrack. But it won't play. The 'Play' icon sometimes flashes and stops, sometimes stays engaged, but the MT cursor doesn't move.

When I try to exit SS, it hangs, and I have to use the Task manager to kill it.

I tried installing another instance of SS64 with no plug-ins and default F-key layout. Same thing.

Possible cause (maybe):

I'm using two monitors. One recently died and I hooked up a new one. All other apps are working fine with it.
A number of software apps have updated recently, but I turn them off and still no go.
Maybe some other setting I've mucked with is causing it?

Funny thing is ... SawStudio 32 still works fine.

I plan to boot into Safe Mode and see if SS64 will work with no background processes, but if anyone has an idea what's going wrong, I'd appreciate any ideas or suggestions.

Thanks.
