I was able to correct the "fullscreen" problem that I reported earlier, be commenting out the line: fullscreen = 0; from the config file: ~/.einstein/einsteinrc The game itself deleted the commented out line on the next run, so I assume it's safe to delete it manually.
could right click / left click be toggled via an on screen button? I nominate the "options" button for replacement. BTW The check is in the mail. Thanks for all your work.
