New beast called Internet Explorer 7 is not yet released, but it seems to show some of new features. They broke something in CSS and because of that text won't display in phpMyAdmin textareas. According to them it is problem in our CSS, but they won't tell where exactly. Why the hell our CSS works fine in all browsers (including MSIE 5.5 and 6) and now suddenly it is broken?
See bug report in phpMyAdmin's tracker for more info.
