Special Characters window no longer resizable in OS X Lion

Question

I upgraded my Mac Pro to OS X Lion (now 10.7.1) a few weeks ago, and am mostly very happy with it. The edge-resizing of Windows is especially nice.

Still, the Special Characters app, which used to have a resizable window from the lower right corner, now has no resizing available at all.

Is there any way to alter this behavior to make this window resizable, or do I just need to wait till Apple recognizes this problem and fixes it?
