I just posted a more detailed description of the problem and it appears to affect other plugins too. I think I’ll try taking all of the plugins out of the plugins folder and trying just Devolution.

By the way Hermann said I should erase the livecode cache. I don’t know where that is, unless he was talking about the browser cache.

If Disk Utility shows no issues with the storage media or format then you may consider a test run in which you first remove any third-party plugins which may interfere with other stacks' activity.
