When using Both Buid 31 and 32 with the option to check spelling as I type I quickly get the following error.

 

Clicking on Debug bring me to the following error.

 

This is only if I have the check spelling as you type option selected.  This happens in BOTH builds 31 and 32.  When I open the project everything is fine but a little scrolling around and typing brings up the error.
