WS_EX_NOACTIVATE flag forbids the window to be activated fix picked from 0.4.15-dev-5137-g826bd41d88(1 of 3 commits for CORE-18417) My reason for picking it is that it fixes CORE-13257 'Reboot leaving Evernote 5.9.8 in tray causes WIN32K BSOD 0x50' I also had to pick together with it the 0.4.15-dev-5491-g1fbed1710eto prevent it from introducing (+2 failures in user32:msg_focus) unittests. ---------------- The above patch allows/encourages us to pick then also: 0.4.15-dev-5492-g47f3a4e144[OSK] Delete WS_EX_NOACTIVATE workaround code (which referenced CORE-18528, but is not fixing this minor GUI glitch yet, it just removes workaround-code that is no longer needed, I just mention the ticket here, because the commit on master did that as well) ---------------- ---------------- The following 2 things were small *unrelated* improvements nearby, and I decided to take them with me: 0.4.15-dev-4323-g9f5cde9cbe[WIN32K:NTUSER] window.c Remove broken assert in NtUserCreateWindowEx. CORE-18123 fixed and a tiny part of 0.4.15-dev-3476-g55a1c29341[WIN32K] appswitch.c: delete unused func DWORD wtodw(const WCHAR *psz) ---------------- and also backport a few whitespace improvements in the files touched.
