Captcha box getting cut off in IE6

Hi All,

I know this is going back a ways to worry about IE6 but my audience isn't all that computer savvy so some of them could still have IE6, actually, one of my sales reps still has it.

This is a sweepstakes entry form so it's real important that it doesn't eliminate anyone from entering.

The catcha box is getting cut off in height to the point where it's usually unreadable. I saved the image from the page display and the entire box is in fact actually there in it's entirety so it must be strictly a CSS display problem. I tried to make a copy of the CSS div.fieldGroup from Standout design and changed it to overflow:hidden and also tried specifying the box size but none of that helped. I've also got a rather wide "submit" button and it's sliding to the right and getting cut off on the right side.

Here's the link to the page:

Thanks,
