Windows on Firefox get stuck

I am having some problems with the latest (2.0) version of dhtmlxwindows.

On Firefox (v 3.02) a simple page rendering a single window (without a viewport) results in the window getting stuck at the top of the page. I can drag the window left and right, but not down into the body of the page.

The following HTML demonstrates (hope this comes out ok):

    FF Test





Test this on FF3 and you will see what I mean.


Ad the following style:

html, body { height: 100%; }
