Thank you all for this information. I appreciate Greg's advice to try a clean driver uninstall.
This appears to be the same problem I am facing with my Epson Perfection V700 Photo scanner. I installed the Windows 1803 update in May when Epson Scan started to crash. I uninstalled and reinstalled the latest scanner driver. I tried rolling back to an
older graphics card driver. I also tried a different usb cable and port. However the problem persisted.
Epson scan crashes when I click on any window outside the Epson scan interface and then click back into Epson scan. Then a blue circle starts turning forever. I have to close Epson scan using the task manager or by right clicking Epson scan in the taskbar/close
and Windows gives the option to send an error report. I have to turn off the scanner and unplug it and start it up again before launching Epson scan again. A reboot is not required.
So I can see I have some choices. Either I can wait for Epson to update the driver or Microsoft to fix the problem or I can downgrade Windows to the older version. In the meantime its still possible to scan as long as I do not click outside the scanner interface
window. After a scanning session I can close Epson scan. Hopefully Microsoft or Epson will fix the problem soon.
Kind regards
Chris
