With jBox, and I think this may apply to Rosa also, the additional
code to display PNGs was only required for older Java VMs. I forget
the exact version of the Sun Java VM in which natvie PNG support was
introduced, but it's been there for 2 or 3 years. So you might try
dislaying PNGs with the non-PNG version of Rosa. The Microsoft Java VM
does not support PNGs, but Microsoft hasn't shipped their VM for a
couple years anyway.

The applete should definetly be cached by the browser. First place I'd
look is at your browser settings. (I often disable caching when I'm
developing pages, and then forget to turn it back on!). The next place
I'd look is at the meta tags in the page header. And lastly, check
that your server and client clocks are reasonably close. (I don't know
much about caching, but I could envision a situation in which your
server was a day ahead of your client, so your client was always
seeing a newer version of the applet, but I may be out in left field
with that...)
