[Qgis-user] layers not displayed in the layer window

[Jens Beutmann]

That seems to be working. Thanx a lot, Yoann!!!
Before running the function, you have to switch on in the layer dialog 
all the layers you want to keep, because otherwise the function kills 
all layers that are not visible. But after doing that, I got the result 
I wanted.
That helped me a lot!
