#1 MenuCracker 1.4 in WinSwitch 3.2.1 went crazy, locked System

[Peter da Silva]

Thousands of system log entries like this, maybe 5-10 per second:

09-01-02 11:12:13 SystemUIServer[471] MenuCracker(ISM): Blocked load of default MenuCracker 2.x bundle.

I only found two menu extras using MenuCracker: iStatmenus and WinSwitch. Uninstalled iStatMenus first, no good. Uninstalled WinSwitch (actually, moved it to '/Library/Menu Extras (disabled)') and the problem is solved.

WinSwitch is version 3.2.1 according to the Info.plist file.
MenuCracker is version 1.4 according to ITS Info.plist file.
