Has anyone experienced unpredictable behaviour when opening files from Explorer? I have never seen such unpredictable behaviour associated with any other application. Shift select four files and open. When I repeat this process very rarely do they all open, sometimes 1, sometimes 2, sometimes 3. Has anyone else seen this?

Also, on occasion, each file will open in a new instance of draftsight instead of opening as windows within one instance of draftsight. Distressingly unpredictable!
