Install Updates - Yad version

[DenW]

Hi Vera/Jerry:  I believe the "problem" of the updates window opening in the top left of the screen is related to the XFCE Setting >Windows Manager Tweaks>Placement where a slider determines the window size for smart placement.  The updates window is usually much larger than the other windows that open during the updates process and would trigger the observed placement unless the slider is say 2/3rds over to the right where I usually put it - I prefer all my windows to open in the center.
