Spry Menu bar wrongly displayed in IE

Question

Hi,
on my website i integrated a Spry Menu bar with one Submenu, which really works fine in Firefox. The boxes have a defined width of 124 px.
My problem is, if you view this site with IE, the drop down menus don´t work and you are asked to activate activeX or scripts. If you do so the whole menu is displayed white unless you roll over the buttons, you can see what actually should be there. Another bug is that the submenus, are oriented horizontally instead of vertically.
Can anyone help me with this nice IE problem?
Thanks a lot !

Hi Ben,
thanks a lot for your great help. I integrated your recommendations in my sprymenubarhorizontal.css file and uploaded it.
When i preview the site in the browser (Dreamweaver -> Preview in Iexplorer) it all looks like it should.
However when i uploaded the new css file, the change is not visible. It´s still the old mistake.
What am i doing wrong? What i also wonder about is, that the css file has a size of 6.554 Bytes. When i upload it, it only has 6.353 bytes.
Can this be correct? Also the SpryMenuBar.js files are different in size.
Do you have any idae what the problem here is?
Thanks again !
Add: I just recognized that also my html. files are different in size. So i guess this is normal. But where is the mistake hiding? I´courious
Or could you pleas check again from your pc in iexplore? Thanks
