Embed Unity in Windows Application (is this a bug?)

Hey guys

I have embedded a unity standalone exe as a viewport into my windows application using the new command parameters available. So here is my issue. I can click on buttons, input text, adjust sliders, but the moment I click in one of the windows app text boxes or even loose focus of the application, when I click in the gui textbox again, I cant type any text. This seems to be text input specific, because the Unity buttons and slider still works fine. Is this a bug?

Sorry, have to bump, no solution yet.
