Not seeing any of our calls in this error report to help narrow down the cause. Could you explain what it was that you were doing when you got this error? Does it happen all the time?

[David B.]

I submitted two errors, one happened when I tried to minimize Launchbox to the system tray, the other happened when I was trying to add roms to the program. Fortunately, they've both only happened once so far.
