BUG: - If you right-click on the desktop to show the context menu, then right-click again, then left-click (or other similar combinations), your next right-click is not registered anymore.
More information: MOUSE_RIGHT_BUTTON_DOWN/MOUSE_RIGHT_BUTTON_UP events are correctly sent from i8042prt driver to mouclass driver, which sends them correctly to win32k. So the problem is in win32k or above
Here is a patch to see mouse buttons events received by win32k: Index: subsys/win32k/ntuser/input.c =================================================================== --- subsys/win32k/ntuser/input.c (revision 16704) +++ subsys/win32k/ntuser/input.c (working copy) @@ -77,6 +77,19 @@ for(i = 0; i < InputCount; i++) { mid = (Data + i); + if (mid->ButtonFlags & (MOUSE_LEFT_BUTTON_DOWN | MOUSE_LEFT_BUTTON_UP | MOUSE_RIGHT_BUTTON_DOWN | MOUSE_RIGHT_BUTTON_UP)) + { + DPRINT1("{ "); + if (mid->ButtonFlags & MOUSE_LEFT_BUTTON_DOWN) + DbgPrint("MOUSE_LEFT_BUTTON_DOWN "); + if (mid->ButtonFlags & MOUSE_LEFT_BUTTON_UP) + DbgPrint("MOUSE_LEFT_BUTTON_UP "); + if (mid->ButtonFlags & MOUSE_RIGHT_BUTTON_DOWN) + DbgPrint("MOUSE_RIGHT_BUTTON_DOWN "); + if (mid->ButtonFlags & MOUSE_RIGHT_BUTTON_UP) + DbgPrint("MOUSE_RIGHT_BUTTON_UP "); + DbgPrint("}\n"); + } mi.dx += mid->LastX; mi.dy += mid->LastY;
