I discovered this problem after I opened and saved several files onto an SD card.  Since the SD card wasn't inserted, the Open Recent menu under File threw a bunch of No Disk errors at me, probably one for each file listed that wasn't accessible.  The pop up lists cancel, try again and continue, but I think cancel and continue are the same and try again will probably repeat this pop-up dialogue.  Something similar to internet browsers' square with a red X in it could be used if an image preview isn't possible.

The most important thing to me is to get rid of the obnoxious pop up error dialogue which can appear multiple times.
