Vladimir, the real problem is that the screen pillars are too short!! If MMC designed new pillars that were taller and with a more logical profile this problem would simply dissapear.
As the top rail needs to be tensioned down over the top of the screen I think a gap (with some sort of seal) will always be needed. I was impressed by the header rail clips used on the Aero 8 and wondered why they were not adopted across the entire range.
