I found that this issue is in conjunction with the following. I did setup the Window Maker to start Emacs when start Window Maker session. I realised that that after WM start but before Emacs24 start I can switch with mouse wheel Workspaces.
So I setup WM to not start Emacs24 automatically. But, this problem remains, because, when I manually start Emacs24, still can't switch between Workspaces with kyboard shortcuts, and with mouse wheel. -- Regards from Pal -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe".
