Something odd but alike related to XFCE 18.104.22.168 and KDE happened to me recently:
When KDE 3.5.5 was released, I decided to replace the nigh-new KDE 3.5.4 install that came with Slackware 11.0.
To do so, I always compile it full as I don't like to install KDE-related TGZ packages if they don't come from slackware's -current, and they always take sometime to make it there. This wasn't the first time that I would be KDE-less for a day or two. Whilst compiling I work in XFCE as this is my office's machine and I must be working somehow
Just to clear out the following paragraph: I'm used to have 4 desktops in KDE and 2 workspaces in XFCE.
This very time that I was compiling, I noticed that XFCE gave me 4 workspaces
instead of the 2 that I had configured before. I gave no importance to the matter and I continued to compile and work. When I had the KDE packages that I wanted already compiled and installed, I went back to KDE to work as I'm used to, though I noticed that KDE was giving me only 2 desktops
I was kind of surprised and confused. I told KDE that I wanted 4 desktops, and after that I went out of KDE and started XFCE again and ooooh surprise, XFCE was giving me 4 workplaces...
Funny, wasn't it?
I guess that from some point in the past, KDE and XFCE started to share configurations. This hadn't happened to me before and being sincere, I didn't like it
Though I haven't found some way to solve this little bugging issue
