So I built the latest fluxbox this past week, and it seems to be working great in DSL.
The 0.9.10 extension was sort of a rushed job, and I found a couple of glitches in it (my fault, not a fluxbox bug). I've got a few configuration tweaks to do for the extension, and I could put it together tomorrow....except I started thinking about making a new style to showcase some of the new features....
If it weren't for the fact that I spent the last 24 hours researching every possible option for fluxbox/init I might have already made a decent style....but such is life.
