Thanks Joe. However, it appears to me that the person who installed
just bought windows that were 1/2" too small. It seems that when he
screwed the window frame to the house, it pulled the frame away from
the actual window. That would account for the 1/8" gap between the
window and the frame. To be sure I am explaining this correctly, I
uploaded a picture of the window he http://www.flickr.com/photos/41436756@N00/393021771/
Thanks again for your help Joe!
