I just happen to have spoken with Diamond Seaglaze about this very subject on Friday. The support person I spoke with said to use a silicone adhesive - or even better- to use a bead of 3M 4200 in seating the handle.
As to the windows sticking - like all of us I've been dealing with sticking windows, and then, sooner-or-later, the handles popping off. Frequent lubing doesn't help for long. In my experience, the tracks pick up lots of heavy soil quickly. The lube may even trap the dirt that creates the sticking.
I was on board recently during a very heavy downpour. My boat was tied up in its slip. The heavy rain was falling on a slight angle from the port side. I left the starboard cabin window (the leeward side) open to enjoy the cooling. After a short time the the runoff from the cabin top dripped into the the window track and flooded it. After closing, the runoff continued dripping down the outside of the glass into the track.
I am looking into installing a gutter along the edge of the panel on the cabin roof side. (I'm speaking of the panel with the dark color trim above the windows.) I think the soil/crud that fouls the window tracks is carried in the runoff from the cabin top. I want to channel that runoff back towards the cockpit and keep it away from the window tracks.
My boat is kept in the water at an open slip. A fair amount of airborne dirt, pollen, bird droppings, spider webs, etc. collects on the cabin top and runs off along with the rain and dew. That's probably where all the crud is coming from. So when time allows I'm going to put some gutters on and see if that will help keep the windows sliding freely.
FWIW - Here's are links to the Diamond Seaglaze info:

Hope this is useful information.
