What types of issues can I expect for users of IE 9 trying to use GP 10 business portal?

Business Portal 4.0 (for GP 10) was released prior to Internet Explorer 9, so the compatibility of the two was never formally verified. Business Portal 5.0 had some issues where the grids didn't line up quite right in IE9, so you may find something similar in Business Portal 4.0.

There is always the issue of not having Active X controls enable/installed. Also use the 32-bit version of IE on 64-bit machines as there are some issues with MBF sections not working correctly.
