Just installed new version Lite0723.674.1050 (2011.07.23) on K3 3.1
Here's the menu:
PDF zoom works fine, but I still cannot figure out where's English menu, so I think I must do an English.txt file by myself and then place it in DK_System \ Lite \ res \ language. I'll modify the Chinese.txt file you Thomass so kindly posted and it should work.
Thanks again
