It would be helpful if some of the menus were "smarter".
For example, if I'm using "Wiggle", then want to use "Shake" - I often just click on the Shake menu.
I shouldn't have to manually "Stop" Wiggle before the Shake menu takes my mouse click.
Then you could end up with the situation that you are doing both processes at once.
Foldit is a slightly different type of "game" to many. There are reasons why things are as they are.
You have not been playing long, play a bit more and you may see the reasoning behind things being as they are
All buttons are start-stop.
Need end one thing b4 you run another.
It is not a bug, it is feature ;]
