Just to comment, I've been running one of the patches between 20-ck1 and this latest one, which is building as I type, but I also run gkrellm here, version 2.2.9. Since I have been running this middle of this series patch, something is killing gkrellm about once a day, and there is nothing in the logs to indicate a problem. I see a blink out of the corner of my eye, and its gone. And it always starts right back up from a kmenu click. No idea if anyone else is experiencing this or not. -- Cheers, Gene "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
