Win11: get screen pixel color without Taskbar flash?

[Craig Newman]

No such issue on Mac, but then again Mac has no taskbar.

On a different note, I made a standard button and field on a new card and placed this in the button script:

on mouseUp
  put the mouseColor into fld 1
end mouseUp

Clicking around various parts of the “main” body of that button, that is, in the blue area as opposed to the white name of the button itself, I get different RGB values. They are all close, but I would have bet that they were all the same.  Nope. The white area that is the name itself is always 255,255,255.

No issue, but why?
