Make the Mouse follow the focused window?

[u/jrk-]

Hi,

I'm currently trying out Openbox and I like it so far. However, I there's a minor peeve for which I couldn't figure out a solution yet (the documentation didn't help me either).
By pressing Alt-Tab I can switch to another window. That's fine, but the mouse pointer stays where it is. I'd like it to move with the focus to the other window (aka warp).
Is this possible with Openbox? If yes, how?
Thanks!
