I am getting a system hang with OO on a CentOS 5 system. Very often when I open a document (double click a desktop document) and then click on the menu the xorg desktop pseudo freezes. The mouse will be able to move in a subset of the current screen but all events go to the netherworld.
ssh in from another computer and "top" reveals that Xorg has 100% of the CPU. Kill -9 xorg and system is fine. I don't have this problem on my FC5/6 machines. I previously have FC5 on this hardware without any OO trouble. CentOS 5 kernel 2.6.18-8.1.3.el5 OpenOffice.org 2.0 680m5(Build:9073) 2 NVidia Quadro 4 dual screen cards four screen xinerama (4096x1280) NVIDIA-Linux-x86-1.0-9755
