I have a database (HTML) of the 2500 movies I've watched and use Netflix descriptions of the films from their website. So while the database is on the screen (using TexPad as my editor) I also have the Netflix page of the movie on screen.

Before the latest Win10 updates (and for the past 5+ years) I was able to switch from one to the other simply by putting the cursor on any part of either one and clicking on it. But now, it won't switch that way. The only way I can switch is to click on the minimize dash on the upper right corner, and then the other is active.

Is there a way to return to the previous way of switching (by just clicking on any part of that mode)?
