I am sorry but never is too lateWhile other openbox users can probably find it, it's always nice to say what settings you fixed. It might save someone time in the future.
In this case, you can find it in the OpenBox wiki, but often your examples help others.

I had x11-wm/fluxbox all the time installed and was use a lot but I had something in my mind, ha ha and switched to Openbox. And first time I installed sysutils/conkyFernandel- Similar openbox setup to yours. I will have to look
closer at your nice refinements. I know that "xml" on my box
does behave rather badly. So I'm sure thankful for sharing these!
