Patch that fixes this bug

I think I have patched this. I was able to find out, that dwStyle for only one
menu was set to MNS_NOTIFYBYPOS, and this is the main menu (the one holding all
items, such as file, view, edit, help). And user32 checks for this menu's flag
(I suppose).

So, I've written this patch, that checks not only current menu style, but also
main menu.

This fixed wrong behavior of WTLIB, while other software I was able to check
works well still.
