About 9 times out of 10, when I invoke Mozilla immediately after reboot/login, many of the controls in the Mozilla window and the contents of the main browser window are partially missing and/or are heavily garbaged. The only cure I have is to reboot again until I get a Mozilla that works. Further invocations of Mozilla are then OK. My home page is usually set to http://www.which.net/whatsnew/contents.html but the problem is present with other home pages.
Build ID ?
Mozilla 1.0.1 Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.0.1) Gecko/20021003
Two further observations: 1. If I login as root, the problems do not occur. 2. If I then logout and login with my regular user name (with *no* reboot), the problems also do not occur. Linux kernel is 2.4.18-17.8.0. I started with the RedHat 8.2 distro, installed Mozilla, then used the RedHat update tool to bring the OS up to date.
Further testing shows that when I first login as root, the problem can still occur, but is less likely to occur than if I login with my regular user name.
Since upgrading the linux kernel to 2.4.18-18.8.0, this problem occurs much less frequently, but it still happens occasionally.
John, is this still an issue with the most recent release/build of Mozilla? If so, have you tried completely uninstalling Mozilla (including deletion of your profile settings in ~/.mozilla) and then reinstalling it to see if that fixes the problem?
