Thanks for this post. You have seen the issue on the usage of the NSSheetMoveHelper. Even if you believe Apple is aware of this issue, I recommend posting a focused sample here to demonstrate the specific problem and how the NSSheetMoveHelper is causing it. That'll help us better understand what's going on. If you're not familiar with preparing a test project, take a look at Creating a test project. If the issue persists after updating to the latest version, I will request that you submit a bug report. Could you please provide the focused sample? Albert Pascual
