Vinyl sash frame separating
I have vinyl replacement windows. Last night I went to close a window and when I pulled down on the finger grab on the bottom sash rail, the rail pulled away from the glass.
It didn't want to pop back into place with hand pressure.
What holds these sash frames to the glass?
(The corners didn't separate. Only the center of the 4' span of the sash frame dipped down--and far enough that I can't close the sash enough to lock it.)

Low quality windows will do that. The glazing tape or silicone that held the glass to the frame has failed. That means you need to remove the glazing stops... remove the igu (double pane glass unit) by cutting the old glazing... Then clean it up and install new glazing. It's important that the glazing be the right thickness for the glass and stops to fit correctly. There is very little tolerance for variation.
Don't try to force it back on or you might crack the glass.

I haven't browsed the ultimate DIY instruction source yet (Youtube) but I'm sure there will be dozens showing how to take apart the sash to replace the tape.
Have you seen one that you thought "that's a good tutorial"?
Yesterday I was reading some 3M foam-core adhesive tape tech literature (for another project actually) and it's clear there are many many similar-looking products that I could choose. Some meant to be permanent, others meant to be serviceable.
What do "high quality" windows use?

Look closely as the part that separated. Some have a tongue and groove that snaps together. It usually takes more than hand pressure to get them to pop together so it might need a block of wood and hammer or a rubber mallet. If it is a glued or taped piece then I would definetely get the proper tape. Some of the better stuff can be found at auto part stores for mounting trim.
