I get the same error.
This is not the first time I have run After Effects on my Intel Macbook Pro.
I just loaded Vers. 7 on the Macbook, I ran some lame project on it too see what it was all about. I get this error when I try to type a new text layer. I have 5 layers of the same STILL image that I put into a pre-comp, then used the text tool in the layer in which the pre-comp was imported.
It won’t let me type now without this error coming up, and the only way I can stop the error is by hitting “ok” and doing an “apple-S” before the next error comes up.
