Hello all, Try the Vistary theme with Preferences setPreference:#browserWindowColor toValue:(Color r: 0.533 g: 0.753 b: 0.976). On the latest OB debugger, I recommend adding some background fill under (in z order) the buttons. As it is now, they live over a background that blends with the source pane, and that end up looking really weird when the source is scrolled. I care deeply about the aesthetics of the debugger, because I spend so much time looking at it :) Bill --- Wilhelm K. Schwab, Ph.D. bschwab AT anest DOT ufl DOT edu
