Win 1.9.7 - window becomes unusable/uninteractable after long idle

Hi folks.
I’ve had a very repeatable bug: Scrivener becomes unclickable after hours of non-use. When I tab to scrivener and click on a line of text or anywhere in the window, I will click on whatever window is below it. If I minimize all windows other than Scrivener, I interact with the Windows desktop. Killing the exe file on the taskbar or task manager and rebooting the program fixes the issue.
