      Which Window Manager are you using?  The code was unable to determine your current desktop number ..

       
    • Blackbox 0.65.0 for FreeBSD 5.2.1-RELEASE

      Sorry, should have mentioned that :)

      That explains it ;)  Blackbox 0.65.0 doesn't use EWMH (NetWM standard), so you can expect it not to work properly.  However, it looks like they're moving toward getting EWMH implemented in the 0.70 release.  Unfortunately, I just tried 0.70.0-beta2 and it still did not work properly with pypanel.  The panel relies on several root window properties which Blackbox is not setting (e.g. _NET_CURRENT_DESKTOP) ..

       
    • Hmm, I'm having the same error under WindowMaker 0.91

       
    • fixed it by commenting 'EWMH = 0' under 'if wm == "wmaker"', I guess WM uses EWMH now.
