To my knowledge (and a search confirms this) I do not have Audio Hijack Pro installed on my macbook pro - details below:

  Model Identifier: MacBookPro4,1

  Processor Name: Intel Core 2 Duo

  Processor Speed: 2.4 GHz

Running OSX 10.5.8

However I have been having problems with the google talk plugin crashing when I try to 'hangout'.  Are there other fixes to this issue?

Thanks!

Damian
