Black color in my tracks list ?? huh ?

[Friedd]

Hi here's a snapshot of my Screen.
From time to time the blue color changes to black on some tracks.
dunno why, nothing special on these tracks.

anyone knows what this means ?

It happens to me all the time, and sometimes to all tracks! But I'm on PT HD3. Reestarting protools make it blue again...

the screen is from a PTLE 7.4 on osX Leopard.
this is pretty weird.
i also have all tracks black sometimes.

i really would like to know what this means.

really nobody ?

Sounds like a possible video card issue.

Can you give us the full specs of your system, including the video card model?

Macbook Pro w/ a 2nd monitor.
somtimes there's just one track black, and somtimes there's more.
sometimes my computer is hot and somtimes it's cold.
sometimes it happens after 6 hours of running and somtimes after 2 minutes.

really weird.

Does this happen without the 2nd monitor attached? Does it happen on the main monitor or the 2nd monitor (or both)? Have you tried different video cables?
