Problem with spell check pop up in rc2 bug?

[Simplemachines Cowboy]

On my test forum this happens.
I notice that it doesn't happen here.
In rc1, the spell check pop up has no scroll bars.
In rc2, there is a vertical scroll bar and the window is too small to see the "Change" "Change All" etc. buttons, unless you scroll down.
In both Firefox 1.5 and IE latest.
It's a little annoying.

Was / Is there a fix?
