Well, my only suggestion was to set usesThreadedAnimation to NO. It may be that that causes Cocoa to use a timer internally, but you shouldn't be doing anything explicit with a timer with respect to the progress indicator.
Yes, we only did usesThreadedAnimation:NO - nothing weird.
Don't do that. You must always shunt such work to the main thread.
Hmm. Has that always been the case with OS X and/or Cocoa? I know an app should not do any drawing from anything but the main thread, but I thought that all the cocoa controls were smart enough to not draw directly when their set* methods are called. E.g., calling setStringValue will set the internal string and do nothing more than call setNeedsDisplay:YES, deferring drawing to the next time the main thread gets some time. Did I forget or never learn something more critical than that?
