461 Save snapshot v. change path

[chrisjj]

Changing right-side folder path is not possible while while left side is saving a snapshot.

[Tim]

The Snapshot dialog is modal to the window that opens it, so no other actions are available. You've suggested before that Snapshots should be modeless and that's still on our wishlist.

Thanks,

[chrisjj]

Sorry - reporting error:

s/is saving a snapshot/is copying to folder/.
