Yesterday Benjamin was having some challenges trying to copy text out of OpenOffice (a full Aqua app) and paste it into an Inkscape (an X11 app) document he was creating. The challenge was that it wasn’t working.
After digging around a bit I discovered that the X11 app didn’t have pasteboard syncing enabled. To fix this we went into the Preferences for the X11 app, selected the Pasteboard tab, and enabled syncing using only the ‘Update PRIMARY when Pasteboard changes’ option. Problem solved!
Unfortunately it also messes up copying and pasting vector images from within Inkscape. Looks like this is a setting that will have to be toggled on and off based on what you want to be doing for your copy/paste action. Rather a pain I think.
