I installed XFCE again on my Zorin 16 Pro and it was fine but I only used it for about 1/2 hour .... yesterday when I fired it up again (after using Gnome for that day) my task bar (which I left at the top of XFCE) was MIA .... so I tried to work it out myself but could find no reason for it to be missing ....
I did make several changes to my Gnome task bar like making it invisible until I hover over it with my mouse .... I know the two desktops are not supposed to be tied together but it does seem strange that the taskbar just disappeared ...
