Edit: Well don't I feel silly. Nevermind.
This is already in...
Look around in the pager options.

So far with fiddling with this feature, it feels buggy.

After resizing the window, I can't click the "SEND" button. I have to hit tab then enter for it to register, since 75% of the time, the button is hidden, the rest of the time, it won't acknowledge clicks.

The window it spawns with is damned tiny and it's cumbersome in that if I click the Pager window on my taskbar (Windows XP, SP2), it just brings that window up, forcing me to double-click the tiny icon in the lower right corner of my screen to use the pager any, such as to join games or start another conversation.

Perhaps this feature could allow it to function in a way akin to MSN (Different spot on the taskbar for IM windows, having the pager and IMs seperate completely)

I can't find any problems with the Send button, myself. It works fine. Also, I can't resize the window below its initial size, so it's impossible to resize it in a way to make the button inaccessible (and increasing the size or anything doesn't break it either, I'm not sure what exact problems you are having).
What resolution are you using?

EDIT: And since you edited your first post, I'll make it clear for other readers that we're discussing the "Keep conversations in separate windows" feature.

It disappeared when I stretched it larger so that I could actually read pages without scrolling, and it randomly appears/disappears during when I'm typing things up. Clicking it still doesn't do a thing for me, but the tab-enter at least hasn't failed me.

Well, this would be more suitable for a Bug Report, with the filled template and all. Perhaps it'd work if you used a more "normal"/common resolution, though?
