Fedora 14 no maximise\minimize text or buttons in apps

[Frank Murphy]

Installed lxde x86 from an F13 liveCD,
yum updated to F14. with
"yum update --releasever=14 fedora-release\*"

then "yum update" and "yum distro-sync"

Have noticed that all the min\max is gone.
Even the panel can be hidden, if a window moved downward.
all used apps have the problem eg. pcmanfm, firefox, terminal,

Unsure if lxde, or a broader problem.
