I just updated my Google Drive to the "new" web interface and I've noticed it is absurdly slow in general.

There seems to be an issue with the Notification Center too (on menu bar). It disappears randomly while Expandrive is open.

Quite buggy, it reminds me why I stopped using it. Shameless plug, sorry!

You're the first to report that, ping support@expandrive.com if you haven't already. I've got gdrive mounted on my desktop now!
