Help - Scrolling Off?

[betsbillabong]

I know this must be a very simple thing that I've accidentally turned off, but when I play my mix, the playhead does not scroll at all - until I reach the end of the song. The window showing the main and sub time periods (right now set to Bars + Beats and Minutes:Seconds, respectively) does not start counting off. Once the sound fades out (where I have it selected to, then the playhead starts moving, and the window shows that I am moving through the bars.

Does anyone know how I inadvertantly did this? I"d like to restore it to normal. I'm not able to bounce, because the entire time it is playing during the bounce, it's not bouncing (the time left remains the same), and it's not till the piece is over that that window starts to go down.

Anyone? I'm on deadline, unfortunately.

Thanks!

PS I don't think it matters in this case, but I am using M-Powered 7.1 with a Firewire 410 on a G4 powerbook... yesterday was working on a ProTools HD setup with a Control|24 and Digi 003 I think.
