Calling NSBeginAlertSheet() from outside the main thread messes up animation

Hi, I want to use NSBeginAlertSheet() to display an alert in a window. The error is detected in a different thread than the main thread, and although NSBeginAlertSheet() works and produces the alert sheet the drawing is messed up.

What happens is that as the sheet animates it is transparent (outlined) or transparent green. If I invoke NSBeginAlertSheet() from the main thread no such problems occur. Everything else works as expected, only the animation is messed up. Anyone have any insight on this (cause and or solution)?

/Bishop
