With the About display open and showing channel information in the Usage tab, clicking on entries in the Groups column posts "Cue <group number> <group label>" to the command line, usually resulting in a syntax error.
I like the idea that you can select groups this way, but it clearly needs fixing.
The bug is active in 2.4.0 and 2.5.0, I will check 2.5.1 when I get home tonight.
