Gabriel Ivăncescu : shell32/autocomplete: Redesign the window proc to trigger on key presses instead of key release.
Module: wine Branch: master Commit: a118459adf218617337c5ea737033fc3bfd9b01c URL: https://source.winehq.org/git/wine.git/?a=commit;h=a118459adf218617337c5ea73... Author: Gabriel Ivăncescu <gabrielopcode(a)gmail.com> Date: Mon Sep 17 22:23:10 2018 +0300 shell32/autocomplete: Redesign the window proc to trigger on key presses instead of key release. AutoComplete currently shows up when the user releases a key, which is wrong. Windows does it when the user presses a key, so use both WM_KEYDOWN and WM_CHAR and redesign it so that it matches Windows behavior.
