As the title states, Glasswire refuses to open within view. No fix for moving it such as focusing and win+arrow keys works. This happened after the most recent update.
I haven’t had this issue myself, but there is another option you could try:
When you have glasswire open on your taskbar, hold shift and press right click, it will bring up a different context menu by doing so. Select move and then use your arrow keys and see if you can bring back the window. It is something that worked for me when I need a window moved or returned.
This finally worked, but it has to be done every time my PC is woken from sleep or restarted. Looks like a windows management issue on Glasswires part
