Internet Explorer quirks with flash

For some reason my website (mdmoms.com) is not working correctly in Internet Explorer. It works fine in Safari and FireFox but in Internet explorer the flash pages you have to click on them to activate it and then it lets you click on the navigation, links, pics, ect. Any ideas, Please help! (Seems to work fine on my wife’s PC, using IE but i think it might be the older version?)

thanks in advanced
