I installed and immediately uninstalled IE7 for 2 reasons.
1. Like said above, I could not customise to my way of doing things - I want the back button on the right.
2. I have a joomla site and IE7 does NOT show anything past a third of the way downwards.
Although I removed it, I wonder what people will see of my joomla site(s) with IE7. This is crazy.
