Fixed text input events with UIM

Alex Baines

I realized overnight that my patch probably broke text input events with UIM, and I confirmed that it does. Can't believe I overlooked that... I've been making stupid mistakes in these patches recently, sorry.

Anyway, *this* one seems to fix it properly. Knowing my luck it probably breaks something else.
