Harmony Remotes

[Smultie]

Dear people,

I'm facing a problem I can't seem to fix.

I got a Macbook Pro 2010 13" for which I bought an Apple Remote (2G, aluminium).

Somehow, I can't seem to get the button below to work on my Harmony.

On my Apple Remote, when I press this button, it switches from fullscreen to windowed (and back when I press it again).

On my Harmony, when I press the OK-button, all that does is play/pause the movie.

I can't "learn" command, since the Harmony won't recognize anything I do with the Apple Remote.

Please help :s
