If any module window is left open for an extended period of time, when I go back to PayWindow, that window is nowhere to be seen and alll other module options are greyed out in the sidebar and top menu, and I'm forced to restart PayWindow. This only recently started happening in the version I had before 20.0.10, which I think was 20.0.7. I was hoping the latest version would fix it, but it didn't.
