I just suffered my first OhmStudio CRASH...whilst operating under the influence of nothing. Thought it would be the first and last, not to be so, CRASHED again on reopening project.
Two days ago, I updated my OS from OSX 10.6.5 to OSX 10.6.8. Would that be a factor?
The Ohm Studio actually crashes a lot. But much less than it used to.
As Peter suggested you can use the Ohm Studio Beta Reporter application to send us a report and hopefully our developpers will be able to solve your problem with the next Ohm Studio update.
You can delete .plist files which names start with: com.ohmforce
If it still crashes I'm afraid I won't be able to help you out this year... because the rest of the team went on holiday. We will release a new version next week that fixes some bugs...
