The links are there, but unfortunately IE6 doesn't support the absolute positioning to keep them on the screen like on other browsers, so the links are uselessly lying in the footer of the page and I can't do much about that.
But I'll look into other ways to make the grids more navigable, and suggest keyboard shortcuts in the meantime. You may find that they are much better than scrolling anyway.
For example, if you press the space bar it scrolls down on your page quickly (two hits and you are at bottom) and the home key takes you to the top. Now you probably already know this, but we also have something nicer that is semi hidden, which are "access keys" you can use to page through the grid even more easily.
For example, in Chrome just pressing Alt+N on the topic list pages will go to the next page (Alt+P) is previous. That is why the "N" and the "P" are underlined on the links as that is a common way to denote that those are the access keys.
IE works almost the same way, but you have to add "Enter" to click the access key link. So if you press Alt+N+Enter it will go to the next page and if you press Alt+P+Enter it will go to the previous page on IE.
Sounds like a bunch, but give it a try. I didn't finish implementing them everywhere I'd like (or as consistently as I'd like) but they can be a much faster way to navigate when you get the hang of it, and I'll do better about making them consistent and accessible site-wide.
