IE 7 seems to work fine for me.

I assume by buttons not showing you mean that you are looking at a blank text area, this means there was a problem loading whizzywig

Weird that it works in mozilla but not IE..  please post your HTML code.  Also if you have modified Whizzywig.js in any way, let us know how.  Of course Im sure you unzipped the buttons to the root directory of your application, but if you haven't - put them there so the browser has no trouble finding them.

Do the buttons show up with the demo on this website?  Are you sure that JavaScript is running with IE 7 or that your firewall is not blocking?

I don't have I.E. 7, but others have used with Whizzywig on my installations, but I'm running a version back.

Good luck and please report back.

Is there some secret to getting the buttons to display in IE 7?  I can only get it to work in Firefox (won't display buttons in Opera either).
