You can set the browser's rect to be offscreen until the page is loaded and
display a "wait..." message or graphic in the rect where the browser will
eventually appear.

It's quite reliable in my application. Something else may be the matter.

One thing I found was that it is important to close the browser as soon as
it is no longer needed. While it is visible, the revBrowser is very
responsive to changing its rect and to calls from my LC scripts to the JS in
the page. But if I forget to close it and other things start being displayed
in its space, that's asking for trouble. Your script, below, does that, so
you already know it. Maybe you need to make sure it's really happening. I
close my browser instances in the same kind of loop, and I haven't seen any
failures. Could there be something in progress in the Web pages that delays
the response?
