The application does not technically crash, however it never continues either.  Once I see the dreaded "Updating responsive grid" progress bar, I know there is nothing to do except ctrl-alt-del to end the task.  I have left the pc idle on this screen for several hours before forcing closed.

This can be frustraiging since all changes are lost and then you get the "The specified project is in use or has not been properly closed correctly. (redundant) Do you want to continue?" prompt.

The only thing I can figure out is that it seems to happen after I copy and paste a page in the map creation section.  The only work around has been to delete the copies and completly recreate them from scratch which takes a lot of time.

Any ideas?
