Chess.com trying to download files to my computer

I've been playing on this site for about six months without a problem. As of today, I'm constantly getting a pop up from IE asking to allow a download from this site.

Does anyone know what Chess.com is trying to download to my computer?

Are there any steps I can take to avoid from having to X out the request every time I change the page.

Thanks

This error might occur because your browser isn't compatible with IE5 content.

Other people are already talking about it. Let's move the discussion there.

What ever was going on has stopped

my computer now says:

"to help protect your security, Internet Exploder blocked this site from downloading files to your computer. Click here for options..."

It's back. This is getting old.
