"Stack overflow in line 0" errors when I look at it in Internet Explorer.

I had an OnError() event in some code that was setting the image source to a default image path if it wasn't found. Of course, if the default image path wasn't found it would trigger the error handler...

For people who have a similar problem but not the same, I guess the cause of this is most likely to be either an unterminated loop, an event handler that triggers itself or something similar that throws the javascript engine into a spin.
