Filled polygon - if filled, text invisible in exported emf
The topic says it all I think.
Anyway, I can describe the issue best like this:
The best way to go around the problem is to repeat the above procedure, but make sure that the polygon is not filled at all. Then it works.
Another thing I see is that any lines in a polygon that is not strictly horisontal or vertical doesn't look nice in the resulting emf file. I know I can use t.ex irfanview to get a screenshot (like the image in pt.3 in the list above) and save as png or wathever format, but I doesn't like that method because when I import the drawing in any application (ex open office) and want to scale it, it's better having a vector picture rather than raster format.
