Green Keyframe Icons KEEP disappearing!

Latest OS X Mocha Version for AE CS5.5
All the time and it appears to be random, the green keyframe Icons keep disappearing. I know they are there as I can jump to the next and previous.
Spending about a day in Mocha on OS X I have gotta say that this software is pretty buggy on latest Snow Leopard.
Cursor wont leave entry field after adding an entry via the keyboard. There are so many totally obvious bugs. Is this software still a public OS X BETA?
If it is… then I can understand all the obvious weirdness of the app.
Anyway, if anyone has any idea of how to get Mocha to refrain from displaying the green keyframe Icons… I sure would like to know !
