In my testing here, I find that Andrew's WINDOW_SIZE function
reports a window size of 1272 by 969 on my 1280 by 1024 display.
This accounts for the taskbar AND window decoration for the TLB,
including the window title bar.

Dick's GetPrimaryScreenSize reports 1280 by 996, which does NOT
include any window decoration (including the window title bar).
Moreover, the /EXCLUDE_TASKBAR keyword only works if the taskbar
property "keep taskbar on top of other windows" is set. If this
property is not set, then the entire window size is returned.
This is identical to what is returned in Get_Window_Size(). That
is to say, not as useful as it could be.

Bottom line, although Andrew's solution is a bit of a kludge, it
does seem to return more useful information if you have the
practical purpose of building a widget program in mind.

Cheers,

David
