actually it did the same for me using 2.0.15 it was a bug in that version. it fixed in .17
as for the mapping keys. i found a work around for the freeze up after you set a key. press the end phone key. the key that looks like a red phone. then press the back key. it should look like an arrow key pointing to the left.
thanks for reply.....
thanks god it had already fixed. but still i cannot load my saved games to 17. that why i'm still playing 15.
about mapping, i have done it too (my previous post). just like you'd said. but it still bugging me. i hope it will fix for next release.
