I should also note that users have hacked around this problem by substituting the libX11.so.6.2.0 from OpenSuse 10.2 for that in OpenSuse 10.3. I would assume this indicates the problem is related to the fact that libX11.so.6.2.0 is now linked to libxcb-xlib.so.0 and libxcb.so.1 perhaps? This workaround also solves the problem under Fedora 8 as well. Jack
