scrollbar question

[larry at significantplanet.org]

I'm using a scrollbar to allow the user to set a value, but I am writing the value to a text file for later use and don't want to constantly update the file as the user drags.

Is there a way to capture the final scrollbar value and then update the file when the user is finished dragging?  I tried "on mouseLeave" but couldn't get that to work.

Thank you in advance!
