Help?

This is my first post. I guess I am a total noob. This isn’t really about flash, it’s about using an swf file. I have made a couple nice rollover buttons for this website, the website was made using frontpage. So, we put the swf in and everything works really well, except for one thing. Using explorer the flash portion of the website doesn’t work unless first clicked on. Otherwise, the box is just outlined when mouseover. It works fine using Mozilla, the page loads and the rollover buttons are ready to go. Is there any way to get it to work better in Explorer?
