I've looked through the online help and from what I can see, this control uses an array, to. So it would have the same problem. I'm trying to download the demo to confirm, but their server must be busy as it's coming down at 1KB/s. Given what I read in the manual, though, I don't think this one would work, either.
Thanks,
Michelle
