kicking,
if you are using netscape, you will need a different plug-in. This probably is not your problem. The help desk in HK has only heard of something like this when the screen was maximized. If you maximize, you need to minimize before trying to change the size. If none of this helps, try logging into a chat if you are on line now and the help desk may provide a few more ideas. At worst, they can get some more details and forward to a techie.
