fix the bugs first

I've installed this on two Win7x64 machines. On both machines it stalls randomly for 1-5 seconds at a time when navigating, and occasionally hangs permanently. While doing that it's not responsive at all. I've killed it once using porcess explorer, and once right clicking the taskbar and choosing close was enough. That's in the first half hour.

I suggest fixing that/those problems before adding even more features or pretending it's ready for widespread use.
