I installed the pbproxy package on my system, which runs Enlightenment window manager and does not use quartz-wm. Wanted to give some feedback. I used install.sh, the behavior of copy/paste was the same as before the installer. I ran top at the terminal to see what was running, and pbproxy was not running. So I just ran it by hand: sudo pbproxy & And then all the copy-paste operations worked great. I'm not sure how the installer intended to set up pbproxy to run, but you might want to adjust the installer so pbproxy runs even when there's a different window manager being used. Text copied fine between Textedit and the terminal, graphics copied fine between Preview and Gimp. I did not test RTF text. What I did test worked perfectly. Hooray! One issue to note with X11.app, the Copy and Paste commands in the OS- X menu, when X11.app is in front, Paste is still greyed out when there is a clipboard buffer. I could paste using the X11 app's own separate menu, but I could not hit command-V. Is this bug documented? On my system, I choose not to run quartz-wm at all, so all I really need to do is add pbproxy to my .xinitrc: source /etc/bashrc pbproxy & exec /usr/local/bin/e16 If pbproxy ends up embedded in another binary, I'll just take out the 2nd line. Hope this feedback is useful. Let me know if you see any issues with my setup or if you want more info. Dave
