--- Comment #18 from Daniel Jelinski djelinski1@gmail.com 2013-01-28 23:39:06 CST --- You mean this sequence: R-down, L-down, L-up, R-up? Actually it fires both NM_RCLICK (in response to WM_LBUTTONDOWN) and NM_CLICK (in response to WM_LBUTTONUP). When you remove WM_LBUTTONUP handler, it will behave correctly.
