change style.height stops loading of page in IE

Hi,

I have a little Flash app that needs to change the size of its height
once it loads. It works in Firefox, Opera and Internet Explorer but I
have come across an issue I need help with. Once the size changes in
IE, it won't load the rest of the page (if the page hasnt' finished
loading all the content). Has anyone else come across this issue? Any
ideas of a workaround I could use?

Thanks!
Kris
