Photoshop :: CC Blank Save As Dialog Then Crash When Working With Video / Frame Animations?

I recently updated to CC from CS6 and am having issues when working with PSDs containing video layers, or are set up as frame animations:  When attempting to Save As, the dialog will be completely blank except for the Save and Cancel buttons.   If I press cancel, then return to Save As, CC then often crashes.
 
Here is the Error Event from Event Viewer:
 
Faulting application name: Photoshop.exe, version: 14.0.0.0, time stamp: 0x5176451b

So far I am only having these issues if I have been working with video layers and then frame animations.  Frame animations in particular seem to cause instability as I can often work with video layers all day without a problem.  Then if I import video frames to layers, or open a PSD containing a frame animation, the Save As may not necessarily work.
 
Sometimes closing and restarting Photoshop will allow me to save again, but then sometimes a whole system reboot is required.  It is only temporary though.
 
I am not running antivirus software or other apps aside from what starts at boot.
