One of our club instructors showed me a method that works well. Go to
the local hobby shop and buy a piece of brass angle, 1/8" X 1/8" X
12".

Good idea, Jim.

Fortunately, preventing these cracks is straight forward. I deal with a fair
number of these little windows while installing Quiet Vent kits for people
on the Minden ramp (gorilla marketing). I always check the tightness of the
rail and flip out window screws and find many that are overtightened. They
should be just finger snug, a few inch pounds of torque. Any tighter and the
rail or canopy will develop cracks.

Also it's a good idea to clean and lubricate the sliding window channels to
prevent wear and tear. I use a Q-tip swab, moistened with silicone spray, to
wipe the sliding surfaces.
