I was able to run Appliance once without any problems.
After that first time, however, I keep getting some weird error:
A box keeps flashing on the top right corner, that switches between "slow keys" and "bouncy keys". Also, a box appear in the centre of the screen, saying "Failed to launch shortcut XF86AudioNext", "Failed to execute child process 'pragha' (no such file or directory)".
These messages keep coming back, even if I dismiss them.
