Thank you.

Hints on where to explore, may be indicated by what OTHER PROGRAMS happen to also misbehave

Temporaily have Windows (Display settings) use the other monitor as Main (and the old main, 'extend the desktop". You may need to drag the positions around: 2:1 instead of 1:2 )

I have always exited Calibre normally. Cannot figure out any possibilities from your suggestions. Thank you for trying to help.

Yes obviously. The question is why does your system think a non-existent monitor exists. The most obvious answer is a monitor was connected to some port such as an alternate video port/tv out etc in the past and is no longer connected now. If that is the case, the question becomes, how to get your system to "forget" that monitor.

@Audra - some long shot ideas - take a system restore point first, search for "create a restore point windows 10", the windows central tutorial is quite good.

Do a test after each 'idea', they are not dependent in any way.

• Do a lightweight registry clean, I favour Piriform's CCleaner.
• Run a System File Check, see >> MS - Using System File Checker in Windows 10 - this takes while.
• With calibre not running, rename its configuration directory to something like calibre_save, and then run calibre - it will build a fresh default configuration directory, and run the Welcome Wizard - what happens if you try to view the Getting Started epub?

To find your configuration folder click the Preferences->Miscellaneous->Open calibre configuration directory button, that will open the directory in File Manager ( it will probably be something like C:\Users\Audra\AppData\Roaming\calibre), close calibre, go up a level and do the rename.

@Audra - this nirsoft tool might provide some clues as to what's going on, and maybe a means to fix it ==>> Enable/disable/configure multiple monitors on Windows
