Image Thumbnail Viewer

[Phiweb]

I've discovered a small problem when running this script in Firefox 1.5. When a thumbnail image is clicked to produce a new draggable larger image, then it is possible to drag the dragbar (including the close button) beneath the toolbars at the top of the browser. Thus it is nearly impossible to close the window. This doesn't happen in IE6. To see the effect, visit: http://homepage.ntlworld.com/colin.philip/phototest/

Has nobody got any solution to this problem? Or am I missing something? Some response would be very welcome.
