Hi Vlad,

Thanks for the info ... Our CMS is actually framed using framesets, so it's
one of the regular frames (the "status bar") that refreshes.  I suggested
the iframe as many other systems are probably not framed.

(btw I would never build a web site with framesets, but for an application
it works very well)

The only issue I have is that if the refresh fails once for any reason, the
frame never gets refreshed and can never try again as the refresh code
doesn't load.

I agree the component sounds like a better idea.  Another approach - how
about some standard javascript in the page, which hits a URL on the server
then reshcedules itself using the setTimeout function?

Cheers
Ben
