Nope, this is the intended design. The standard drawing model for Cocoa on OS X is that views draw into a single context for the whole window. Normally then views draw their content *atop* any existing content, so as to build up the correct result. e.g. you composite a translucent colour *over* the existing graphics there. By using NSRectFill you are instead *replacing* whatever is there with your translucent colour. Consequently, whatever is behind the window is now free to appear through that translucency. As Uli said, you want to use a different compositing operation, to give the correct result. _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
