The best KB I found for my ACL is SwiftKey Tablet v 4.0.1.128. The latest version cuts the bottom of the KB off (the Powered by OpenMobile section overlay) which is not very good but this older version is great.

Messed about with build.prop a bit to no avail. I now just use my CM 11 install to backup apps that I want. I'm too scared to mess about too much incase it breaks ACL and I have to Dr by TP again.
