Rated 5 out of 5 stars
I've always loved the classic interface and have kept using some version of Qute since it came out.
Sadly this theme seems to have transparency issues or something running on my systems of windows 7, when viewing pdfs with the acrobat plugin. Whatever is behind the browser window can be seen and makes reading pdf documents somewhat hard.
My quick fix is to leave a paint window open with a solid black image.
Thank you for your report! It will be fixed in the next version, which you can try out by installing the development version 1.5.3b1.
