(for Mac) I have lost about 12 hours of work so far because of a bug in Photoshop for video. If you go to Export > Render Frames, then open the options menu (for export settings), this menu can easily be trapped behind the Photoshop-windows. If this happen, Photoshop will stand-by (with the rotating circle icon), and thereby freeze, waiting for me to click OK or Cancel on the options-menu, but this menu is hidden by Photoshop. If I force quit for Photoshop, the Options-menu is accessible as soon as Photoshop shuts down, which is too late.
