[jQuery] setting height of popup multiple times, background image still shows in IE6

[jQuery] setting height of popup multiple times, background image still shows in IE6


I have a hidden popup that I populate with content and it dynamically
expands to the size of the content.
I then show the popup.
When a user clicks on another link, it populates the popup with longer
or shorter content.
When the content is SHORTER, it seems to show the background image
that I'm using expanding to the height of the previous size of the
popup.
I've tried setting the height manually with JS, no luck.
This only happens on IE6.
Any suggestions would be much appreciated.
Thanks,
Andy
