Yes, I took the update and yes I am having lots of problems. KeePassX will not open. Netbeans 6.5.1, SQL Developer will not display. The applications are running if you look at the system monitor. I have to kill them to get rid of them. Today, I could not even click on any icon on the desktop. My work around so far has been to shutdown the machine and wait a few minutes, restart and cross my fingers that I get the magically bug report. When I click on KeePassX after a reboot and I get a bugreport, everything starts working again. Here is what was updated on my system yesterday ...
I have attached the bug report and it looks like the problem is in libX11 which was updated yesterday. Let me know if the file does not get attached.
Please, please test before you release. This is now the 3rd major problem since Fedora 10 was released. I had no problems like this with Fedora 7, 8, or 9. What gives with 10?
