b. Apple Guide slow launch: Additions file add launch time Whatever else may be causing slow Apple Guide launch times, one thing is clear: the more Apple Guide files Additions files you have installed in Extensions folder, the longer the Apple Guide launch will take.

a. Apple Guide and Speech conflict After updating to 7.6 or 7.6.1, Neale Langman reports that accessing Apple Guide may result in a system crash - and may even result in a corrupted Apple Guide file that will then need to be reinstalled. Neale claims to have isolated the problem to an Apple Guide conflict with Speech Manager 1.4 extension and Speech 1.5 control panel. He says that Apple Tech Support confirmed the problem and is expected to post a statement about this shortly.
