a phantom onscreen keyboard appears that I cannot use

[Alex Liberman]

when I enable screen keyboard either thru a keyboard shortcut or via the universal access menu there is a transparent square where the onscreen keyboard should be. Clicking on it does nothing. I also tried building the latest caribou with the same result.
