Just thought it was worth reporting this weird crash in case anyone else has it.
Win 7 64 - Running under remote desktop.
Load Omni 2.6 into C3. Open GUI, Crash.
Repeated 4 times.
Load Omni standalone - OK
Load Omni into Reaper - OK
Turn off remote desktop and try using locally.
C3 loads Omni, no problem.
Turn on remote desktop.
Now C3 loads Omni.
