Positive it's enabled. It seems like it's the theme because all I was doing was messsing about with the PSX (Playstation 1) emulators, which is why I saw your theme in the "All Apps" list. So I installed it while taking a break. Then I went back to messing about with the PSX emus and the OSK failed to function.

There are a few posts in this thread about "missing buttons on the OSK", so there does seem to be precedent for the theme interfering with the OSK in one way or another.

I tried to install the Addon pack #1 to see if maybe it would improve things, but no improvement. So I set everything to default and uninstalled, reverting back to the default Nokia theme. But still, no OSK. It looks like I'll have to reflash. Any suggestions/comments?
