I think I have a similar problem with MicroEmu. I can start Opera Mini, but when I try to enter any kind of text (for example, to log into Facebook), I am given a text entry box. I can enter text into this box, but the OK in the lower right corner of the box doesn't do anything.

Now, if this isn't your problem, if it is that your keyboard input doesn't seem to work, try the keyboard input focus hack. When your app is on the screen, press the power button. When the menu pops up, press somewhere outside the menu so that it goes away. That usually works to give keyboard to the app.
