Hi,
Unfortunately, PageLines does not support Internet Explorer 7 nor provide support for issues related to that browser version. IE7 is extremely poor, slow, old and doesn't support HTML5 or CSS3 which is what PageLines Framework uses. I suggest informing these users that they're currently not experiencing the internet as it was intended and are putting there computers at risk, they should upgrade their browser as soon as possible.
Tell them to read the Browser Happy website, which will help them understand -
