This is weird.
I know for sure that (at least on Windows) there are exist 2 different
According to the MSDN (ref.

LBS_MULTIPLESEL - Turns string selection on or off each time the user
clicks or double-clicks a string in the list box. The user can select
any number of strings.
LBS_EXTENDEDSEL - Allows multiple items to be selected by using the
SHIFT key and the mouse or special key combinations.

I interpret this as following:
Using 1, I can select multiple string with just a mouse click if the
string is not being selected. If the string is already selected, it
becomes deselected without selection clearing on any other previously
selected string.
Using 2, I can extend the selection, i.e. pressing Shift, I can select
continuous string, i.e. select 1,2,3 and 4 strings with just 2 clicks.
Or using Ctrl, I can select multiple strings.

And this is exactly the behavior I see on Windows. And it is NOT how
it behaves on *nix/GTK.

Maybe all your Windows programs were using LBS_EXTENDEDSEL?

Also, I think I will need to test my Cocoa apps as its possible I
forgot what it did. Sorry about that. I will do that tonight.

Thank you.
