Problem with Vista IE8 and Dialog

Problem with Vista IE8 and Dialog

Hi ,
I noticed that IE 8 (8.0.6001.18828) with Windows Vista renders jqueryUI
dialogs unusable (weird blocks, some parts are transparent, etc).
The same source with Win XP and IE 6 -> 8 works fine.
I was trying to figure why's that and noticed that bgiframe plugin has same sort of influence.
When I removed loading of bgiframe plugin and commented out, 'bgiframe: true' from my
dialog constructors source, dialogs appeared fine also with Vista.
Is this a known problem and is there a better way to handle it?
