The new AtariAge theme doesn't look good in Win7 Internet Explorer 11.
The main page is way too wide for the screen and you need to scroll Left<>Right to see everything, and there is a lot of whitespace
When you enter into a forum, then everything fits on the page, but it is rather squished on the right margin.
When you enter into a post, then it looks normal.
I tested a few different resolutions, and this attached video has my computer set to 1920x1080
The video is 20meg, so I zipped it and it is much smaller (sorry I don't have much of any screenshot recording software).
The other themes look using Internet Explorer.
When using Chrome, then everything looks good with the AtariAge theme
