If the Screenshot Monitor application unexpectedly crashes or strange errors occurs it very helpful for us to get the application local trace log to resolve the issue. You can provide us the log with the issue report using the following instruction:

  1. Open a Finder 
  2. Application log is available by the full path : /Applications/Screenshot Monitor.app/Contents/Mono Bundle/data/SMTrace.log 
  3. Attach the file SMTrace.log to the email with the issue report.
