Thank you for confirming my suspicion that multiple Qt Creator instances were 
fighting over the data C:\Users\esutton\AppData\Roaming\Nokia\qtcreator\

Thank you for the suggested work around.  While I love Qt Creator it may be 
easier to force myself to never use more than one instance of Qt Creator at a 
time when working under Windows.

Unfortunately this is an annoying issue for Windows users of Qt Creator.   
Under Linux I find multiple instance of Qt Creator very useful.  I wish I could 
use it the same under Windows.

Thanks again for your suggested work-around!
