SD can't find my startup volume!
 

Just downloaded and installed the upgrade (after running into the auto-upgrade problem others have apparently seen).

It seems that neither the old version (1.5.5) nor the new one can find my startup volume! Which is the volume they were launched from! (in /Applications/Utilities)

It's definitely there and I can use it normally with any other program.

As I indicated in the support email, I'm not sure what you mean by "can't find the startup volume". If you're getting a sheet, did you do anything to the startup volume that might have caused its low-level ID to change, like erasing it with Disk Utility?

If you cancel the "mount sheet", can you pick the drive in the source pop-up?
