This behavior is often caused by a preferences file getting into a state where it can't be written to. Deleting the file will cause it to be recreated and fix the problem. To locate the file:


  1. Open Solo and go to the "Help → About Solo" menu and note the "Preferences Path".
  2. Navigate to that folder in Windows Explorer and locate the "matlabprefs.mat" file there.
  3. DELETE that preferences file, then restart Solo.


  1. At the Matlab command line run the following command and locate your preferences folder:
  2. Depending on your system, locate either "matlabprefs.mat" or "preferences.mat" in the preferences folder and delete it.
  3. Restart Matlab.
