This will close issue #4113--sadly, this issue is an issue that is beyond our reach to try fixing within GTK. --- diff --git a/README.win32 b/README.win32 index 704f6f3caf..f208a49ed9 100644 --- a/README.win32 +++ b/README.win32 @@ -3,6 +3,22 @@ The Win32 backend in GTK+ is not as stable or correct as the X11 one.
