Just to let you know that ScreenCaptor has much improved my scanner usage.
I have an old Cannon Scanner which is no longer supported by the manufacturer - who suggests I buy a new one.
The problem is that the old software does not work very well in Windows 10 due to driver problems. I have had to use it in a Windows XP Virtual Machine - still not ideal performance.
Your software gets it to work perfectly (even faster) in Windows 10.
