"Startup Disk Creator" on 31 May quantal install said it created USB flash O.K. of the 1 June daily i386.iso.
On booting, the cursor was a black X instead of an arrow, there was no top panel, and no launcher. The Install and Example icons were on the purple splotch background.
Precise "Startup Disk Creator" ran just fine and the USB flash installed O.K. Well, a code 2 on time zone, Colin's got a fix for that, and the usual _usr_lib_gnome-settings-daemon_gnome-settings-daemon.1000.crash which doesn't seem to cause any trouble.
