Hi Mirek,

See the switching Ctrls/hwnds for WM_POINTER and WM_MOUSEMOVE messages while on top of menu:

[+     0 ms] WM_MOUSEMOVE  N3Upp7MenuBarE  : 0x6a82880 (hwnd 0xd3009a)
[+     0 ms] Ctrl::DoMouse() [141, 302]
[+     0 ms] MEvent0 [138, 19]
[+     0 ms] mouseCtrl != this
[+     0 ms] HasMouse() = false
[+     0 ms] HasFocus() = true
[+     0 ms] HasMouse() = true
[+     0 ms] HasFocus() = false
[+     0 ms] HasMouse() = false
[+     0 ms] HasFocus() = true
[+     0 ms] HasMouse() = true
[+     0 ms] MEvent0 [138, 19]
[+    15 ms] WM_POINTERUPDATE 5UWord  : 0x6b88070 (hwnd 0x7c02b4)
[+     0 ms] Ctrl::DoMouse() [141, 343]
[+     0 ms] MEvent0 [141, 197]
[+     0 ms] mouseCtrl != this
[+     0 ms] HasFocus() = false
[+     0 ms] HasMouse() = false
[+     0 ms] HasMouse() = true
[+     0 ms] HasMouse() = false
[+     0 ms] HasMouse() = true
[+     0 ms] WM_POINTERUPDATE 5UWord  : 0x6b88070 (hwnd 0x7c02b4)
[+     0 ms] Ctrl::DoMouse() [142, 343]
[+     0 ms] MEvent0 [142, 197]
[+     0 ms] MEvent0 [142, 197]
[+    16 ms] MEvent0 [142, 197]
[+     0 ms] WM_MOUSEMOVE  N3Upp7MenuBarE  : 0x6a82880 (hwnd 0xd3009a)
[+     0 ms] Ctrl::DoMouse() [142, 302]
[+     0 ms] MEvent0 [139, 19]
[+     0 ms] mouseCtrl != this
[+     0 ms] HasMouse() = false
[+     0 ms] HasFocus() = true

Although not shown here, the screen coordinates come in right for both events, but the translation differs in DoMouse() because the events end up in different Ctrls/hwnds. Therefore, also local coordinates mismatch. As you can see, WM_POINTERUPDATE lands in main window, whereas WM_MOUSEMOVE goes to drop down menu just as it should.

Hope this helps...

Best regards,

Tom

EDIT: Plain hovering on an open drop down menu makes both WM_POINTERUPDATE and WM_MOUSEMOVE land in the drop down menu:

Drag is the difference...
