In using my Epson Scanner with the Smart Panel, I seemed to have lost the Scanning window that displays all of my scanned documents. It appears on my Windows Taskbar, but when I click (or Alt-Tab) to switch to it, the cursor flies to the upper left-hand corner of my monitor off the screen!
Solution: Right-click on the program in the task bar and select move. The cursor changes to a cross-arrow type of icon. Now use your arrow keys to get it back on the screen.
Thanks to Tim H. for looking this up! Unfortunately, when I got back home to try it…it did appear to be trying to move the window, but it was still hidden from view!!!!
