sorry about the missing info, here it is.
================================
On one particular logic song I have a problem where it takes like 20 seconds for the computer to start playing the song or do most functions except for view different tracks. And then when it does start playing the song there is no sound coming out and the levels are not showing on the individual tracks or on the master track. the levels are showing in the arrange window though.

factors;
-other songs work fine
-cpu is not being pushed hard
-does it also when I have airport off (regarding that firmware bug that was going around)

I have a
-macbook pro
-logic pro 7

Thanks
