When working with a raster image in the background I am not able to window select objects that are on top of the raster even if the raster layer is locked or frozen. It is still possible to select objects individually, but with many of them it quickly becomes very annoying. Window selection is still possible if it is started outside the raster, but that's a very makeshift workaround.

I didn't have this problem in AutoCad.

Any ideas?
