Textbox delete bug

Thanks Bob.  That at least gives me an idea of what I can do to keep the exception from happening in my app.  I tried looking on Microsoft's connect site but could not find anywhere to submit Windows Phone bugs.  If anyone could point me to a place to submit bug reports, that would be great.

Mick, I have been able to reproduce the bug on the device and emulator, as Bob said.

Thanks for the help,
Josh
