when opening a SFTP connection via the adhic Ribbon, the SFTP Connection gets openend successfully.
Directly after opening, when switch to another open terminal sessions, the adhoc Ribbon for SFTP is grayed out.
Switching the tabs again, the SFTP adhoc ribbon can be used again.
So just on the first switch from the now active SFTP connection to another terminal session, the adhoc ribbon is not working...
thank you for reporting the issue. The next release will have that fixed.
