Hi Greg - don't forget that handy little doohickey in the audioedit window that help you align your vocal. Use in small phrases - highlight the "out of time" section, then press the ctrl key and the left mouse button at the same time, then slide the highlighted phrase as you need to put it on beat. Oh yeh, do this on a duplicate track. Try to sort it out with sliding. Or as Mario suggested - phrase at a time. If your vocal is coming in late for the whole song, then maybe it is a driver matter, but if it is just now and then, then it is a timing problem with you and your backing tracks.
Maybe for recording you need to boost the beat, or insert a percussion track to help you with your rhythm vocal cues.
Failing that, maybe trim the lyrics.

Good Luck - hope this helps. Ian
