Victor,

If you're using the Web browser control part of the reason it's so slow is that you're effectively using IE 7 by default. Lots of JS optimization has occurred since then.

You can force a different version of IE in the Web Browser control for your application via registry keys and that should improve performance significantly especially if you target IE 9.

Here's more info:

>I have hit the same wall. Explorer is slooooow with Javascript and Google Maps, but I have to have it inside a VFP form. The firefox activex is very, very old and only works with FF 1.x, the chrome one is a way to control the browser but you can't host it in a form, if I see the docs correctly. If you found a solution please post it
