--- Comment #2 from François Gouget fgouget@codeweavers.com --- Created attachment 70311 --> https://bugs.winehq.org/attachment.cgi?id=70311 user32:win Dump the 0x7fff messages
The attached patch shows that the 0x7fff message is not sent to one of the windows created by the test.
win.c:4042: Test failed: hwnd 00010306 message 7fff win.c:55: hwnd=000201D6 pid=8080 tid=2128 now=84671 win.c:56: hwnd=00010306 message=7fff wParam=302 lParam=0 time=84671 pt=(250,250) win.c:60: wnd: parent=00000000 owner=00000000 win.c:65: wnd: pid=8080 tid=2128 class=46 L"{A028AE76-01B1-46C2-99C4-ACD9858AE02F}.message" text=0 L"" win.c:72: hwnd=00010306 is a message-only window
So it is sent: * To a windows with the class "{A028AE76-01B1-46C2-99C4-ACD9858AE02F}.message". This class seems to be related to the Korean IME. * And that window is a message-only window. * This is the case for both the user32:input and user32:win tests.
