Aha! So you're grabbing the slider's pixel position & using that to map back to the position within the sound? You're probably getting rounding error (I did). The solution that I have found in this situation is to always get the slider position as a percentage of it's total available travel and the then set the sound position as this percentage of the duration. Then you are guaranteed that all pixel positions will map within the duration. Also you should special-case the 100% situation, since you can't play from #startTime = .duration anyway. hth -Buzz >Anyway, thanks all, the key frames thing made sense. > >-Natalia > > > >[To remove yourself from this list, or to change to digest mode, go to >http://www.penworks.com/lingo-l.cgi To post messages to the list, >email [EMAIL PROTECTED] (Problems, email [EMAIL PROTECTED]) >Lingo-L is for learning and helping with programming Lingo.
