Opacity tool doesn't work?!
Hi!
I'm trying to create a map that shows different types of buildings and I want the different shapes to be transparent to show the building and streets in the back. What I want is coloured shapes marking different areas on top of the map but still showing the background map.
But I can't get it to work!
When I change the opacity all that happens is that the colour gets lighter until it is completely white, almost as if it is "cutting through" the background instead of showing it?! And the background map is locked.
Please help!!
