No, it doesn't
I started to download some updates. I checked XP, Vista and 7 32-bit, and wanted to make a cross-platform ISO.
It started and later just closed without notice.
Here's the last lines from the log:
07/06/2011 14:17:55,11 - Info: Downloaded/validated 13 statically defined updates for w60 glb

...and that's it.
And now it doesn't open, even without the pen drive.
