??IE?? screwsup rollover w/sound

[nchan]

Hi,
Got an image swap with behaviour play sound, works in Netscape just fine. If fact I have another file with this script 'n it works in both browsers. It works very smooth, a nice effect. I've tried applets, but they seem jumpy to me and I can't use transparent images with 'em

I can't seem to get this one going. IE wants to play it by opening another window.
Anyone out there familiar with this problem?
Here's the problem page.
