[Javascript] "Multiple" Select controls and popup objects.

[Peter Brunone]

H,

    I don't have my home dev machine in front of me or I'd test instead of asking, but... don't the Netscape/Mozilla family browsers have the same problem with select elements?

    If not, then that makes a few of my upcoming tasks a lot easier...

Cheers,

Peter
