A simple JavaScript should suit your needs.=20
I dont have my book in front of me right now for specifics, but I do know
there is a function called "onLoad" that will force a reloaded page each

resize of the screen. Etc...etc...=20
Any JavaScript book will be extremely informative of these little tricks
and is well worth the investment.=20
