When opening an image window, PixInsight doesn't give focus to the new window. So if you have a bunch of image "Views", and you try to save them, You might find that all the saved versions have the same image. Please look at the attached files. the first "PI_BeforeClick1.jpg" shows PixInsight prior to my restoring an image window. The next file "PI_AfterClick1.jpg" shows PixInsight after I click the square box to "restore" an image. Notice that the restored image does not have the focus. So when I choose "File/Save As" from the menu, the wrong file gets saved. Totally Counter-Intuitive.
My system is running Microsoft Windows 10 (version 1703) and PI version "01.08.05.1583 Ripley (x64)". When you restore a window it should have the focus.
I must confess that the latest version is awesome, can't live without it!
