I'm using Internet Explorer 6 sp3 and everybody's leaning on me to upgrade my browser. I accidentally upgraded to IE7 once and was miserable with it and went back to IE6. A friend that upgraded my computer memory once loaded Firefox and that was dreadful. I'm quite happy with IE6, with the exception that sites I link to sometimes overlay graphics demanding that I upgrade and I can't see what I went looking for. I'm fairly useless on the computer - it's taken me five years to become proficient with IE6- and I have a strong preference for staying with what I know. My mind isn't closed to alternatives (assuming there's something out there that similar to what I'm used to) but I need to understand the process. Can I load a second browser onto the computer for test-drive purposes? When Firefox and IE6 were on in tamden things slowed 'way down. I'm reluctant to erase IE6 unless I know I can live with whatever I'm trying out. Also, would like to know...Is there any really good reason to change? I know that the constant upgrading BS seems to be the norm with computers, but in most respects I'm very satisfied with what it does right now.
