I've had my app running on the iPhone for months now with no issues whatsoever.

However, when I'm trying to use the openGL performance tool, my app runs on the iPhone perfectly well, but the performance tool stops, with a yellow bar and the message: "Target terminated too early to collect data."

Has anyone else experienced this? I've read the documentation on how to use the program, but nothing much seems to indicate what causes this.

And no, my app is definitely not terminating. :-P
