I think I have found a bug.
Patch some fixtures (for example some Par64).
Switch to the "live" tab.
Switch to the Par64, but disable the "Show palette" and "Show the group window".
Now try to change one of the faders - it is not possible, I can't move them.
Only when I enable "Show the group window", select the fixtures and disable "Show the group window" I am able to move the faders.
A simmilar bug occurs in the "setup" tab:
Switch to the Par64, but disable the "Show palette" and "Show the group window".
Now try to change one of the faders - this is possible, but you cannot "slide" them.
Only when I enable "Show the group window", select the fixtures and disable "Show the group window" I am able to "slide" the faders.
I am using the latest version (April 11 2014).
