This bug was fixed a short while ago, however, I'm sure Rich is waiting until the next major upgrade comes out before they upgrade the software here.
If you compare the style of UBB here on TheFiringline.com with BladeForums.com, you'll notice quite a few custom modifications, all of which have to be coded back in every time there is an upgrade. Rather than wasting time doing this for every minor bug fix, it's better to wait for a stablized version to come out, then customize away.
