Skype OSX crash from preferences > notifications
This post has nothing to do with my mission work. Just to let you know.
I’ve had a problem in trying to change notifications in the Skype Preferences pane (I’m using OS X, by the way). But, every time I clicked on the red flag (Notifications), Skype would freeze for up to a minute, then crash. BOO!
With some help through the Skype forums, I have fixed my problem with a small deletion. Apparently the text to speech feature, the voice of Alex to be exact, caused the problem. Being a dedicated non-text to speech user, I had no problem ridding of my new enemy. I went to the following location and deleted the Alex.SpeechVoice folder.
Main HD > System > Library > Speech > Voices
If you happen to stumble upon this post and have pulled out numerous hairs, I hope this helps more than Rogaine.

Wow. I couldn’t find the answer to this anywhere. You’re a lifesaver. Thanks so much.
You should rename the folder instead of deleting it in case you ever need it again. I renamed the folder to Alex.SpeechVoice.backup and it fixed the issue.
Thanks for posting this!
