Don't worry, it's fine. It is part of the emergency evaluator safety 
net. If you are doing something in Morphic that causes an unrecoverable 
error, such that a debugger cannot be opened in the Morphic framework, 
then the system will try to switch over to that root MVC project and 
open a debugger using MVC. Finally, that fails again, the system will 
drop you into the traditional emergency evaluator. 
This allows many kinds of failures that involve the user interface 
itself to be handled in another framework. It can be very helpful 
if you are working on Morphic itself and make a mistake the breaks 
your user interface. 
The release image now provides a root MVC project for this reason. 
If you are planning to do work in MVC that might breeak the MVC user 
interface, then you would want to work in an MVC project that has 
a morphic project as a parent. The same emergency evaluation mechanism 
will apply there, such that if you break something in MVC the system 
will try to open a Morphic debugger.
