I have an issue when attempting to save files to jpg as per the screenshot..if I save it as any other format, exit P.N then run it then open the saved file then it will sometimes save, mostly that error pops up and am not able to save the image.. Ver 3.5.11, on Win7/64 Clicking Save button will give the "There was an unspecified error while saving the file" pop-up message.
