Created Issue: Cannot access a disposed object error after copy/paste/rename file [993]

VS 2013, Dev 2014-05-16

I made a copy of an existing file in the project, using solution explorer, I select the jade file, ctrl-c, ctrl-v, then F2, typed a new name and got this error when I hit enter:
```
---------------------------
Microsoft Visual Studio
---------------------------
Cannot access a disposed object.

Object name: 'MarshalingWindowFrame'.
---------------------------
OK
