Transparent NSWindow And mouseDown Events

I'm using a transparent NSWindow containing an NSSearchField so that I
can do search over my NSOpenGLView-based app. Everything works well
but switching between the front and back view requires two mouse
clicks as the first is used for changing focus. This gives the
impression that the app is irresponsive when in fact it's waiting for
the second click.

Is there a way to get a -mouseDown event *and* a change of focus at
the same time?

Yes I know about layer-backed views but they look awful in that mode
(tons of aliasing). I also know that CoreAnimation is a more elegant
way to mix Cocoa controls with OpenGL, but I don't have the time to
rewrite this release.

Any help would be greatly appreciated,
