Hi, thanks a lot for the patch, unselecting now works all the time.

However with my own application, there still remains the second problem,
which i is my fault i guess, as i can't recreate it with the example
application. 
Maybe someone has an idea what exactly might be the problem without reading
my code which surely would be a pain for u ;)

My second problem is: When i unselect multiple features, only one of them
gets redrawn as unselected. The selectedfeatures-array of the layer is empty
however.

Thanks in advance
Florian
