Modal dialog in IE - non-bgiframe solution?

Modal dialog in IE - non-bgiframe solution?


A jQuery dialog of mine was modal in Firefox (right) but not modal in
IE (wrong). I looked around and saw some comments about using the
bgiframe plugin. I'm lazy, and that looked like too much work, so I
tried using a 1x1 transparent GIF as the background for the overlay
pane:
$("#dialog").dialog( { modal: true, overlay: { "background-
image": "pane.gif)" } } );
That seemed to work, even when the content beneath the overlay pane
included SELECT elements.
BUT... I only tested in IE7, and I am not an expert on this issue. I'm
going to test in IE6, too, but I have to start up the old model T to
do that...
Should I avoid the transparent GIF method described above in favor of
the bgiframe solution, and if so, why?
Thanks!
