The original tracks were supposedly cut on a reversed 45 to allow water to run out but I think depends on who was doing the cutting that day. Its just not enough drain area. The water & dirt will collect in the track and override the inside track and dribble down the teak walls.
The new tracks should really have the very inside track the highest and ALL the other tracks lower but that's a manufacturing issue.
I suppose a table saw could cut all 3 tracks down but may be risky to cut that much off.
Another idea.
I think there are 4 tracks total (2 windows and 1 screen). If you just cut down all but the inner track just a little back from each end I think that may promote good drainage.
Looking top down. Inside cabin track remains longer.

I know this does not help with removing the glass but I'm more concerned about water dribbling in a damaging the wood than I am about pulling glass.
That's my theory on the subject.
I may pull my windows this year and do this if I can find the energy.
