Complete Control Over Windows Explorer

I'm using Windows Vista and DOpus doesn't seem to have complete control over Windows Explorer. Let me explain, when I'm in a different program ie. Notepad and click File, Open, the open dialog box seems to be Windows Explorer & not DOpus. I find this box limits my functionality & I wondered if there is a DOpus replacement, plugin or option that I can change?

Hope someone can help.

Thanks in-advance.

No, that is not possible. See here.
