"Apple has discovered an issue that can cause a system crash when running Mac OS 7.6 and applications using QuickTime. Although this issue can be encountered using any application which uses QuickTime, it will most likely be encountered when using high end video editing programs and large QuickTime files. Increasing the memory allocation for the application may help avoid this. This issue occurs only with Mac OS 7.6; it does not occur with System 7.5.5 or earlier versions of system software. Apple is working on a solution."
