Yafaray and Mac OS X.5

I have installed the latest Yafaray on my Mac and when I go to Render using Yafaray 0.0.3 and then hit render the strangest thing happens: the Yafaray Render Window does not stay and I cannot find it. I have both Yafray and Yafaray installed.
Thanx,
DJ

I also have both 2.5.3 and 2.5.5 installed because of Yafray. I will try this week to see if I delete the Yafray scripts and just have one version of Python fixes it.
