Apple has released an official fix for the Blue Screen problem after Leopard has been installed.
There are 2 approaches you can take. One of them is installing the system as a fresh install by running the OS X Leopard Installer again and selecting the Archive and Install option. This option is available after the Select a destination screen.
Doing this will install an entirely new copy of the OS and will move your existing Mac OS X system files to a folder named Previous System. Choose the Preserve Users and Network Settings option to archive user accounts and their home folders.
A second solution is available to try if you are familiar with using Terminal. This solution can help remedy problems caused by third party software references that are not compatible with Leopard. The following steps will remove these references:

2. Type these commands and press Enter after each one is typed (be careful):
/sbin/fsck -fy
/sbin/mount -uw /
rm -rf /System/Library/SystemConfiguration/ApplicationEnhancer.bundle
3. Restart your Mac.

So far I’ve gotta say I am very impressed with the new Mac OS, Leopard. The features in iChat are worth it alone. The many different ways you can collaborate and share files is just amazing. I know there are Windows alternatives, but Leopard just makes it so easy. The Time Machine and the easy ability to create desktop gadgets are also very impressive.
The only problem so far seems to be with the menu bar being hard to see. They have made the decision to go with a transparent effect that just doesn’t work for users running higher resolutions, or people with vision problems.
Chris Pirillo tested it out on his live webshow and stated that he will go 100% Mac after getting Leopard. I think many will follow, including myself. Yes! It’s that friggin’ impressive to me! Also check out this article: Leopard: Faster, Easier Than Vista
