I have imac OSX version 10.9.5 and running CS6 extended. Within last couple of weeks it is freezing (coloured ball rotates annoyingly) and more recently I cannot save or even close. I have to force quit. The type tool seems to want to initialise every time I want to use it?
Let's look at Fonts first.
One suggestion in this thread is to go through this doc for basic font troubleshooting.
