It has happened to me twice (once with 2.3.3_rc5, xorg-server 1.4.2- apple41 and the other time on a Tiger machine with a macports x11- server 1.4.2-apple41) that all clipboard proxying from X11 to the mac clipboard stopped working. It only happened after X11 had been running for a few days straight, but I saw no suspicious errors or warnings in the console log. I suspect that switching to a different user and/or putting the machine to sleep might have induced this, but this is only a guess. In the X11 Pasteboard preferences, I have all of the options checked. Out of habit, I usually do a Command-C in X11 when I want to transfer some text to the mac clipboard, but for these two times even the Command-C no longer worked. It was as if the X11 server completely lost communication with the mac clipboard. Quitting and restarting X11 brought back the clipboard proxying. Have you seen or heard about any behavior like this, or is there any changes in 1.4.2-apple42 that may affect this? Thanks, Martin Otte
