I just installed six Milgard brand vinyl windows. One of the windows
stays ajar a bit up at the top.

There is a part at the bottom of the window frame, which I will call
"rail". It is shown on one of my photos. I am not sure if this is the
proper name of this. The bottom of the frame for the pane straddles
this, and it slides over this.

I'm noticing that the "rail" rises a bit towards the left end. I
think this is causing the bottom front of the sliding window pane to
tilt slightly up when it is pushed closed, which in turn is causing
the window to stay ajar up at the top.

I'm wondering if I can remove this "rail" without destroying it. If
Ican remove it, I am planning to raise the middle of it so that back
end of the pane can be even with the front when it's closed.

The following link has two photos of the window:

Do you have a square? Check it out. My money is on your window being
square but the installation is not. If I'm reading your explanation of
the "symptoms" correctly, the frame is racked. If that window frame's
corners are all at a perfect 90 degrees, then the problem is the window
itself. Can you remove the window itself from the frame and check to
see if there might be piece missing (I'm thinking some sort of contact
point, like a teflon or Delrin piece, which assists the window to slide)?
