Fancy zones not enumerating all monitors

[Andypro1]

Environment

Windows build number: 10.0.19041.264
PowerToys version: 0.18.1
PowerToy module for which you are reporting the bug (if applicable): Fancy Zones

Steps to reproduce

Run fancy zones editor; drag to any of my three monitors.
My three monitors are all 1920x1200 and are in portrait, landscape, portrait from left to right like:
| - |

Expected behavior

Fancy zones should recognize all three monitors.

Actual behavior

Attempting to edit a custom zone always puts the new movable zone window in the middle monitor and I cannot drag it to any other monitor.

Screenshots

My zones-settings.json shows only a single device which may be the issue. I am running the three monitors from my relatively old AMD Radeon HD 6950 card. Windows has no issues with displaying extended desktops on all.

Hi @Andypro1
you may be affected by this bug #611
Just to make sure, when you try to assign a layout to a monitor you open the FZ editor on that monitor?

Thanks enricogior -

After reading issue #611, it looks like I just didn't know how to initialize Fancy Zones on the other monitors by moving the mouse to them before opening it. Looks like it's working now. Will close this as a non-issue.
