First, I think the default "click to toggle!" tooltip should be removed.

Second, there is a one-pixel space inside the draggable splitter area where the mouse icon displays as the default pointer instead of a set of arrows.

Third, this example demonstrates the splitter is only limited on the right side of the screen:

Use SetSplitterOrientation() to programatically flip the side of the splitter pane, or alternatively specify the SPLIT_CANFLIP behaviour flag using SetSplitterBehavior() to allow the user to do it themselves.

P.S. Where does the code you posted differ from the 'CreateSplitter' example?

SetSplitterBehavior()

The splitter should stop at the left and right sides of the screen.

The SPLIT_VERTICAL constant is for use with SetSplitterOrientation() only. See the docs for SetSplitterBehavior() for the constants supported with that command...

e.g.

SetSplitterBehavior spltmain,SPLIT_CANFLIP|SPLIT_CLICKTOTOGGLE

Hmm,
although Josh took the wrong constant I could simulate the problem when using the resize flag.
e.g. SetSplitterBehavior spltmain,SPLIT_RESIZABLE|SPLIT_CANORIENTATE
It is then possible to drag the split far out of the left/top of the window. And it jumps back to the correct position when you resize the window.

I could simulate the problem when using the resize flag.

SPLIT_LIMITPANESIZE was implemented to prevent this problem.

jsp	(Posted 2010) [#7]

OK, but that is used for a different behavoir. Of course the problem does not show up with limitpanesize or with canflip, because the splitter does act different then.

SPLIT_LIMITPANESIZE The splitter side-pane is not allowed to take up more than half the splitted dimensions.

That means you can't have the full size or suffer ;)
