Apple QuickTime 7.2 Bug.
On July 11th, 2007, Apple released QuickTime version 7.2.
If you installed this update on a PowerPC machine it will cause Variations2 to fail to launch with the error NoClassDefFoundError:quicktime/internal/jdirect/Linker.
If you installed this update on a Windows machine it will cause the audio player to get stuck 'buffering' the track and will not play.
We are currently working on a fix for these problems.
