After starting from Import > Document (from ExactScan)…, I check the box in ExactScan Capture to use the scanner’s own interface.
It is confusing which settings are in effect: those in the ExactScan Capture dialogs or those in the scanner’s own interface. I’d suggest removing duplicated options from ExactScan once control is turned over to another interface.
When scanning multiple pages the Scanning more pages dialog (Stop and Add) is buried in the center of the screen underneath any large scanner interface window from another interface. I’d suggest always bringing it frontmost. It is confusing when nothing is happening and the application is waiting for input but with no visible dialog.
The OCR Activity window is in the lower left of the screen and also sometimes buried underneath any window that happens to be in that area. Again, bring it frontmost.
