Well I have to say using object desktop mgr is never dull. Things keep morphing; I'm trying different combinations to find a stable one. Firefox interacts strangely at times with any appearance changes; it doen't close but instead acts like a retracted group and has to be closed with File/Exit from the taskbar, which is still visible even after the close icon is clicked; etc., etc.
It's not breaking anything, it's just unusual weirdness that is hard to nail down, as some changes bring new effects.
Overall I'm enjoying it, and it is teaching me the Manager as well.
