It turns out that the Edit window was off screen. We were able to move it back; however, Adagio does not remember the new position so that when we log off and back on the Edit Window is again off screen.
Also confirmed that on my PC that Adagio Ledger does not save the window position or size for the Edit Window in version 9.1. Same may be true for other functions from the Edit Window. Can Tech support confirm that this is not operating as it should?
