I logged a support call and the issue is resolved so I just thought I'd share it with the community. Should anyone else encounter the same issue please refer to the response below (my issue was caused by the second entry (IssueID 64336):
There are a couple of known issues that I think
relate to this behavior.
There is issue ID 66695: where minimized objects are not shown in AJAX when
using IE9 or IE 10 (but work fine in IE 8, Chrome or Firefox).
There is also issue ID 64336: where minimized objects are now shown in AJAX if
the file name contains a parenthesis symbol ().
Both of these issues have been reproduced in house by our R&D department
and fixes are currently being developed.
Can you verify if the issue is reproducible in a different browser or if the
QVW file name contains symbols that are not letters?
