Now that I have it set up to play BT, Snowager, and scratchcards, I see what you mean about that.
Happens quite frequently, and I would rate my proxies at 7-8/10 as far as dependability.
The only other thing I'd recommend, or maybe you already know of a way to do it faster, but if I want more or less the same settings for all of my shells, an "Add to all users" would be great for scheduling. I'm only using 8 accounts right now, but I imagine it would be super tedious for more than say, 15-20. No big deal though, only have to set up the schedule once. Took me 15 minutes for 8 accounts to set up the schedule because of the newness and my desire to make things look more legit.
