Bouncing Individual Tracks Out Of Pt6 Options

[dualdelay]

I've been using Pro Tools 6.1 for about 6 months now. Up until recently, I used to be able to hi-lite a given set of tracks within along the same time line frame and bounce them to whatever stereo format I chose, seperately from everything else in the Pro Tools file I was working in. For some reason, when I try to do this now, Pro Tools automatically begins to bounce all the tracks in the file starting from the begining of all tracks, instead of the ones I just hi-lited. Had anyone seen this or know what settings regulate the bounce functions?

Also, I read in the manual that you can export individual tracks using the export -> audio regions as audio option, although I haven't been able to nail down where to find that option for 'audio regions'.

I appreciate any and all help!

thanks,

Victor
