I'm having the launching problem, too, but it works from the command line (although it takes a few tries sometimes; I don't know why).

Actually, the one weird problem that's popped up for me -- and I was wondering if anyone else has seen this -- is that I'm having an issue where I visit a webpage (as an example, let's say I'm trying to reply to a thread on 4chan, because it happens all of the time on there now where it wasn't before), and the browser wants to download the whole webpage. If I'm on a page where it happens often as the page is loading (like Facebook), I'll see a request to save the page faster than I can hit cancel.

It's not like it's bugging me any; I'm just curious if anyone else has seen this pop up yet.
