Bridge opens wrong image(s), randomly switches to Photoshop desktop (all recent CC versions)

Since one or five updates ago Bridge CC (Windows 10) has been all new wonky--it does this on both a Ryzen and Intel computer, so two distinct installations. I only use raw images. Bridge will frequently open the wrong image. That is confirmed by closing the converter and seeing that the image I indeed wanted to open is still framed as the chosen one--having just happened for umpteenth time that is the reason for this post. Or Bridge will open more than one image sequentially but, again, closing the converter finds but one thumbnail image outlined as selected. Last but not least annoying is that while pulling on the slider or paging through thumnails (Bridge is in thumbnail view mode) the already open PS desktop is invoked/switched to--the mouse cursor could not have accidentally slipped to the PS icon because I removed the icon from the taskbar to test that.

The Intel installation is actually recent so uninstalling and reinstalling ain't gonna do nothing.
