Well, after doing some more testing it appears this is a KDE issue.
If I switch my desktop environment to XFCE everything works as
expected; I get desktop icons on both desktops and full mouse control
in both.  I can switch the mouse/keyboard focus back and forth without
any problems.  Unfortunately the very reason I'm trying to adjust my
Xserver settings is to be able to use KDE desktop effects on my
"general purpose" desktop, so I'll guess I'll have to do some more
digging and perhaps seek assistance in the Fedora/KDE forums.

Allan, thanks for your help in troubleshooting this issue.  If not for
your posts I would still be thinking I was configuring something wrong
in my xorg.conf.  Just out of curiosity, what desktop environment and
version are you running?

Thanks,
John
