Hi Diplocaulus,
It looks like quite a few users are experiencing similar problems, but unfortunately I was unable to reproduce the problem on the test device.
If it is convenient, could you please record a video of the current popover problem and provide it to me?
Best regards,

Hi Mitchell,
It's not an issue that really requires a video demonstration. I'm working in another app when randomly, without warning, an already-opened Explorer window will pop to the foreground, disrupting the work I'm doing in the app. If I happen to be mouse-clicking when this happens, then the mouse-click will suddenly be applied to the Explorer window. Very disruptive.
I've been using Microsoft Windows since version 2, and it's been my experience that 99% of the time these sorts of issues are a fault within the operating system. Pardon my cynicism, but on a related issue I've been having ongoing problems with Microsoft Outlook for over a year that Microsoft support has repeated told me will be fixed "soon."
