This looks like an issue with scrollbar/trackbar actually (at least the
message matches exceptions they throw). Can you post the stack trace?

Curious... I'm not loading any images specifically (I've disabled the
one splash screen image I have). The only other graphics that could be
loaded would be the application icon I suppose, but the error seems to
be triggered by the painting of a control inside of a user defined
control. Is there a good way to debug this... I haven't yet figured out
a decent way to thoroughly debug my mono apps yet... how do you guys
debug these things?

Sounds like something in the image loading code. Do you mind filing a 
bug report and attaching the image that's failing?
