strange resize quirk with javascript

[jon ps]

I've wasted a day on this now, and can't find anything anywhere on it. So maybe someone here can save me. Please!

I have a host flash movie, from which I launch another flash movie in a pop-up - using getURL with a javascript function (no problems this far). I run into this problem when I try to resize the pop-up window using another javascript function (triggered by getURL command on a button). This time:

function resizeIt(newwidth, newheight)
{
        self.resizeTo(newwidth, newheight);

} 

simple... surely!

Well it seems IE on mac wont allow me to resize the window below about 200px width and about 350px height. Is there a way around this? Or has anyone come across this before? Also, on Safari, the resize crops the window by about 40 px (could possibly do a work around, so perhaps not a problem).

Thanks Jon

ok. still no joy. But with further faffing, it seems with IE (i'm testing on 5.2 OS X), once a browser window has already been built, it can then no longer be resized below certain dimensions: 336 px wide x 206 px high.
I can't find any documentation about this. Has anyone come across this or know of a work around? Do I just have to live with it? Or am i just being an idiot?
I'm dying here. Please... someone...
