Error dialog boxes in AOZ Viewer cover up AOZ Viewer window.
Because of this, there is no way to view the failed output for diagnosis.
Either or both of the following can be utilized to fix this:
The error boxes should be movable so the user can see the failed output.
Closing the error box should NOT automatically close the AOZ Viewer.
(This also prevents viewing the failed output.)
This is not a problem when running in a web browser, since the browser window remains open.
(See screen snapshot for example.)
