Save-as crash/freeze using Qt5 on Windows 7 on a Dell [SPR00042]
The Dell Backup and Recovery tool on Windows 7 causes Qt5 applications (such as the viewer) to crash when opening a file manager dialog e.g. using “Save Image As”. After the crash Windows 7 will adjust the way in which the viewer runs which will prevent a crash for the affected dialog window only. However, the dialog will be blank except “Save” and “Cancel” buttons. Pressing the “Cancel” button and then trying again will work around the issue for that dialog until the viewer quits. The process must be repeated for the other file dialogs.

Uninstalling the Dell Backup and Recovery tool will resolve the issue.
