OK, so I took out the icedtea and installed the Sun JDK 1.6.0_03. Now when I try to run a simple java program I get the following message. java: xcb_xlib.c:50: xcb_xlib_unlock: Assertion `c->xlib.lock' failed. Aborted I've never seen this before and don't know where to start to make it work. Any ideas? Thanks, -- Knute Johnson Molon Labe...
