[Plugin: NextGEN Scroll Gallery] IE issues

When I use the code [sG_imagesSolo id=12] the slideshow works great in Firefox and Chrome, but I get a scroll bar in IE9. I can hit F12 and refresh the page, and everything works well. When I close and reopen IE, the scroll bar returns.

Adding the thumbnails back in (with [scrollGallery id=12]) works without issue – the scroll bar only appears when I use the imagesSolo option.

I know it’s probably a Microsoft issue, but is there anything I can do to make the imageSolo option work in IE without having to hit F12?

Here is an example gallery:
