Hi, Alex.
I checked your survey in IE 7. It looks okay. I don’t have IE6. But let me give you a couple of suggestions that might help. If these don’t work, get back to us and we will have a tech test it with IE6.
1. Try using the Embeddable theme for your survey. I think your survey will look better and it may solve the problem.
To switch the theme, go to Look&Feel -> Click to switch themes.
2. Try the iframe option for embedding your survey on the Publishing page. If you use this option, you will need to adjust the width and height in the css.
I hope this helps, Alex.
