Squash / Succhini pollination?

7:53 am in Plants, Seeking Advice by Trygve Henriksen

Does anyone have any experience with Squash / Succhini?

I have two of a ‘midnight’(miniature) variety in my WF.
(Picture in this post: http://our.windowfarms.org/2010/10/23/update-on-my-wf/ )

Both have grown to decent size and bloomed many times, but I have been unable to get them pollinated.

Is there a special trick to this?
