Question
RASTERIZE remains greyed out
I am fairly new with Photoshop (CS3 Extended) so please bear with me.
I have a file with a layer that I want to rasterize.

When I right click on the layer the rasterize option is greyed out and also if I select Layer and Rasterize.
If I merge down with the previous layer or insert an empty layer underneath it remains greyed out and unavailable.
Any suggestions?
Thanks
