Check Browser Compatibility, Cross Platform Browser Test - Browsershots http://browsershots.org This is a cool website that gets actual people to screenshot based on different OS and browsers, takes a while for it to come back but very very useful.
Browsershots is a great website the only downfall is that the maker Johann C. Rocholl has given up on the website.
Helped me with a bunch of sites when I was having compatibility issues with new designs made for my clients. I use it to spot the compatibility issue and then I load my virtual machine and test the design there under the browser under which the design has issues. I fix the design and voila: my client has a perfect functional design.
I used it on my last web design and found it to be quite useful since I don't have all the browsers installed on my work computer! Highly recommended!
