For the last few versions, Screenshot Captor (Portable) has been attempting (and failing) to open the most recent PDF file (based on extension) that is in my [Downloads] special folder during startup. While I originally thought it was some setting in my configuration file that was causing it, a brand new download (ie, with no settings) does the same thing. I can keep the error message from being displayed only by removing all PDF files in the directory, but as soon as a new PDF shows up (which happens all the time: it's my Downloads folder), the next startup will cause the same error once again.
