I use IE8 and haven't noticed anything buggy about the upgrade. BTW, when you do download it, the new version will just overwrite over the old version. No need to uninstall.
I have IE, as well as Firefox and Safari. My dad uses IE, and I have had this computer for like a year. I have not updated or installed anything for IE. Now I found out there is an IE8, do I need this? Is it buggy or does it have problems? Do I delete the existing IE and then down load 8?
Thanks in advanced,
