Even if I disconnect the other monitor so that the system only sees one monitor in display settings, Calibre won't display. It shows in the task manager, but it's not displaying anywhere (I looked for it using the recommendations above).

Any thoughts? is this a known issue?

Thanks.
Try the following...

Plug in both monitors. Run Calibre. Make sure everything with Calibre is displaying on the main monitor. Turn off the secondary monitor and if Calibre is displaying correctly on the main monitor, close Calibre, reboot, make sure the main monitor's graphics card is set as the main graphics card. Then try Calibre.
