Is there a way to let KMZ's only show borders...?

[J van E]

I use KMZ's to make sure I am planning flights within FTX regions. However, when I load those KMZ's I get lots of icons etc. which I don't want because thay completely clutter up the map. Is there an easy way to only show the borders of the regions? Using the P and M radio buttons didn't give me what I want. Or is the only way to solve this to create my own KMZ's? I tried to do so but failed miserably (after spending hours on it).

I can add it to the wish list...

I tried kmz-files with self-made polygons but they also do not show on the map.
With working kmz-files I can deselect "P" for polygons and this works, polygons are hidden.
Deselecting "M" for markers unfortunately do not work. This would realize J van E's wish.

There are some files it just doesn't recognise as having content. I've sent reports to the makers of the kml library in the hopes that they'll issue a fix.
