In Laserfiche 11, user navigates to correct folder, Scan button becomes blue. User clicks Scan button, and scan page opens up, and freezes, with mouse cursor showing loading wheel. Everything on the UI is unclickable and the window cannot be X'd out. Cannot access Scanner Setup option to try and troubleshoot. Only way to close it is through Task Manager. This has happened on two different workstations with the same scanner. Nothing has been changed, except that the scanner/printer was moved to a different corner of the room, so it was temporarily unplugged. But the printer functions fine. It is a Konica bizhub c368.
