make DSOFramer object either not visible or transparent

I have a dsoframer object on a form. The form has the background that is in with my company's style - using a background image.
Before anything is loaded into the dsoframer window, it is just a blank window (or whatever colour is set for backcolor).
I'd like to either make it invisible until i use some code to make it load a document, or be transparent.

Its Visible property doesnt seem to affect its visibility.

Thanks
