Steps to reproduce
Start with the Dynalist Windows desktop app closed. Connect an external monitor to a laptop. Open Dynalist Windows desktop app. Move the Dynalist window to the external screen. Disconnect the external monitor.
The Dynalist window should show up on the laptop’s main screen after the external monitor is disconnected. All other apps I use do this when an external monitor is disconnected.
The Dynalist window will no longer be visible. Left-clicking the Dynalist taskbar icon to minimize or restore the window does not make it visible. Closing Dynalist and re-opening it does not make it visible. It seems to be “stuck” on the external monitor that is no longer there. If the external monitor is re-connected, the Dynalist window will be visible again, on the external monitor.
Windows 10 version 10.0.17134…
Dynalist Windows desktop app version 1.1.13
This issue was reported in the past in this bug report: Invisible Dynalist window?
The suggested solution was to follow the steps here: https://support.microsoft.com/en-us/help/181691/some-programs-are-displayed-off-the-screen
These steps work, but I feel that they are a work-around for a flaw in the Dynalist app. As mentioned above, no other Windows app that I use has this issue, so it seems like a bug to me. Also, following the steps in the Microsoft link are a hassle.
