My virtual keyboard seems to have gone invisible - when it activates, all I see is a big empty black space where the keys should be. I still see the white textbox with an active cursor, and in the top left corner of the keyboard area I have a dropdown arrow that I can dismiss the keyboard with.

But that's it. The keys are not just invisible, they are not there - pressing the area does nothing.

I must admit, I was mucking about trying to free up some root space, and I might have deleted some hildon-type thing. That's just a big guess, though - I was trying to update Knots and it told me I was missing a "libhildon". That could be unrelated coincidence though, I don't know.

Does anyone have any experience or solution to this problem? I'm not really looking forward to reflashing, if I don't have to. I was able to update to the new firmware today, and that didn't help, fwiw.

Thanks for any help.
