Hi,
When starting GTK+ programs on CJK (Chinese, Japanese, Korean) Windows, the IM context code (hence the IME support code) will be activated automatically, so it is both unecessary (and causing crashes) to send a gtk-im-module settings change event afterwards in gdkevents-win32.c when we, say, for instance, change from a Chinese input method to a Korean input method (or vice-versa), or when we activate any IME input method when one is not activated yet.
With blessings, thank you!
