Some users are reporting problems launching Classic or running Classic applications after updating to Mac OS X 10.4.9.

Fixes
Replace Classic Startup.app In some cases, the following file:
- System/Library/CoreServices/Classic Startup.app
can become problematic after an incremental Mac OS X update. Try removing this file and replacing it with a copy from a system that has a known working Classic environment.
Remove DiVX component Some users experiencing this issue may be subject to a conflict caused by the QuickTime DiVX 5.2 component. This file is located in the /Library/QuickTime folder. If you are having problems starting Classic, try removing the DiVX component from this folder, and attempt to re-launch Classic.
Remove Classic control panels In some cases, problems with Classic startup or Classic applications can be caused by problematic control panels. Try removing groups of control panels then re-attempting the previous operation. Some users have had success with removing the control panel "Apple Menu Options."

Upon upgrading to Tiger I found that Classic froze when starting up, well before it ever tried to load extensions. The solution, after digging through the Apple messages boards (and finding several others with a similar problem) is pretty bizarre: go to /Library/Application Support and rename the folder "DivXNetworks" to "DivX Networks". Why something that is only part of OS X (the Application Support folder) would freeze Classic is a mystery, but changing this folder name did solve the problem.
What people didn't mention on the message boards is that this is causing QuickTime to not load the files within this folder, as shown by the following message in the console: 2005-07-29 07:51:26.164 Eudora[2104] CFLog (21): Error loading /Library/QuickTime/DivX 5.component/Contents/MacOS/DivX 5: error code 4, error number 0 (Library not loaded: /Library/Application Support/DivXNetworks/liblame3.92.dylib
In any case, no other ill effects have been noticed, and Classic boots right up now.
