cant move/resize window after closing binder

Running on Windows 10, version - 30 Oct 2018 (not beta)

In the last day or so, whenever I’m running Scrivener in a window, I lose the ability to move or resize it after closing the binder/collections pane. Everything inside the window works just fine (navigating, editing, menus…) but the window title bar and edge borders become non-interactive. Closing Scrivener and reopening the project fixes it temporarily until I close the binder pane again. Anyone else experience this?
