Spry MenuBar1 IE Issue

Question

Website works great in FFX 16 and Chrome 21, IE 9 has issues displaying the menu, and it does as well in IE8 or 7 if I use the developer tool to look at compatability. The menu should have the top menu items going from right to left, instead in IE it goes from top to bottom.
suppose to look like this:
instead in IE it looks like this once I accept the Active X pop-up:
Here's the CSS:

BROWSER HACKS: the hacks below should not be changed unless you are an expert
/* HACK FOR IE: to make sure the sub menus show above form controls, we underlay each submenu with an iframe */
ul.MenuBarHorizontal iframe
          position: absolute;
          z-index: 1010;
          filter:alpha(opacity:0.1);
/* HACK FOR IE: to stabilize appearance of menu items; the slash in float is to keep IE 5.0 from parsing */
@media screen, projection
          ul.MenuBarHorizontal li.MenuBarItemIE
          display: inline;
          f\loat: none;
          background: #FFF;

Fixed my own issue after playing long enough. Commenting out the entire section for browser hacks worked! Now it looks great in IE 9, 8, & 7
