The latest version of IE is 7. IE 8 i dont think will be out for another couple of years.
If it is IE 7, Mini uses it all the time and its the second most used browser on this site and there are no issues like that, and then theres IE 6 which is still the most popular browser on our site, and I havnt heard anything from anybody else about it not working. So I am unsure.
Could you take a screenshots of the problems and upload it to the gallery? (press the prnt screen button, go to "paint" under program files > applications > paint, then when in paint, click edit then click paste, then save as. Make sure you save it as a JPG or PNG or you wont be able to upload it to the gallery).
Thanks,
Pierce
