MLX for Realtors

If you mean MLS, most of those sites are not supoprted on any browser other than Internet Explorer for Windows and therefore won't work on the iPad. So your only opton would be a third party app from the app store if any are available.

Checking google, there are quite a number of MLX "products". Is this an iPad app on the App Store? Or is it a web site? What are you doing to "open" it and what happens when you do.
