Okay so maybe I am just coding this wrong or maybe this is an actual bug. I am currently building with TI 1.3 and iPad 3.2. The keyboard toolbar in landscape mode pops up vertical. In fact the only direction it works in is that one portrait mode. Photos below.
Looks like you have found a bug - it would be most helpful if you could:
create an app.js file that could be dropped into an app to reproduce the problem
report the bug, with an explanation and example to reproduce, on our Lighthouse issue tracking site.
I've got the same problem with iPhone. Ti. 1.3 and iPhone 3.2
