title: Specify popup size for a Dotnetopenauth OpenID Provider
body: <p>I am implementing a SSO solution for a controlled set of web sites using Dotnetopenauth. It's really cool once you get the hang of it. </p>
  
  <p>I am using the SelectorProviderButton on the RP side, as this handles all the popup stuff automatically. However, the size of the popup is huge - basically the size of a full web page, and thus obscures the RP page behind it. I have put a javascript set size on the OP login page, but the user can actually see it busy resizing. </p>
  
  <p>So the question is, can the size of the popup be specified somewhere when using the SelectorProviderButton  (either on RP or OP), so that it is of manageable dimensions, such as when calling google, yahoo etc?</p>
  
  <p>Thanks, </p>
