I use BoxCryptor with DropBox, on a Mac running 10.8.2. The password is saved.
Every time I open BoxCryptor, it mounts a new virtual drive on the desktop, in addition to (an identical) virtual drive that was open when I last quit the program. If I don't eject one of the two virtual drives, the next time I open BoxCryptor there are three identical drives, one labeled with with a "(2)" and one labelled with a "(3)".
Initially I had BoxCryptor open automatically with my login items. Then I turned that off and now open manually. Either way I have the same problem.
It isn't a huge deal, but I do find it to be a hassle to have to manually eject the drive every time I sit down.
Is there any way to have BoxCryptor mount one, and only one, virtual drive at a time?
