OK, get a standard browser window open in IE... press F11....

Looks pretty tidy.

Open a browser window with these options in JavaScript....
"fullscreen=0,toolbar=0,scrollbars=1,location=0,st atusbar=0,menubar=0,resizable=1,width=0,height=0"

Looks feckin' horrible.

Do the same in Firefox and it's really tidy... but I suspect me going back to my boss and saying "tell the client to install Firefox" will be met with an unhealthy mix of incredulity and derision.

Any ideas?
