Zach - Thanks for responding. Version number is "wine-1.0" using your command in Terminal. I'm not 100% positive but I am pretty sure I had Firefox 3 running in my prior build of Darwine which was downloaded from http://www.kronenberg.org/darwine/. I had to switch to the version from http://thisismyinter.net/?p=47 to enable printing. (You can see my thread in this forum http://forum.winehq.org/viewtopic.php?t=1558 if it is of any help.) Should I uninstall Firefox 3 and go back to version Firefox 2? Will I break gecko if I uninstall Firefox? That X11 error is interesting because part of my rebuild this morning included downloading and installing X11 from Xquartz which I thought was supposed to get me past all of those Apple X11 errors. Really appreciate the input. bob
