Thanks so much for playing, and for the great feedback! You're not the only one who has forgotten to clock out, really should've prioritised creating a prompt when the quota had been reached. Lesson learned.
Sorry about the cursor bug, I did have issues occasionally where it would refuse to "enter" a machine but never had that cursor bug you're talking about. Perhaps they're linked, will look into it and see if I can solve it for peace of mind, thanks for mentioning it!
