X and Fluxbox :: Middle click emulation

Hi all, I was running DSL 0.7.2 or something like that, but accidentaly broke it =) so I took the opportunity to install 1.0.1. Good job, by the way, it's come a long way, and the MyDSL is great. Anyway, the only problem is the built in (laptop) PS2 mouse doesn't middle click when I press both buttons. It did it the old DSL, though, which is the confusing thing. I told xsetup.sh that I had 2 buttons, and .xserverrc has the -2button option set. Any ideas?
