If I open a folder containing images from MS Paint or any other app, they display as expected, never a hesitation. (Is this related to the P.N open folder view never retaining my selected view? ie, Thumbnails, Tiles, Icons, List, Details?) Lately, I open P.N using "Open with" on a file, as when I open P.N then browse for a file, it freezes when in the Open file dialog, I try to display List instead of the Thumbnail view that always appears.
