Hey PX,
I suffered some of the same issues as you earlier today but managed to get
it all solved. You say you've done all that the other posters suggested
(version=1.0.0, separate gml parse/read, and redraw your highlights layer)
but have another look.
Separating the GML parse/read solved it for me ...
Peace out, SFS
