Disabling TF3D landscape (even with keyboard out)

[xternal]

I have been searching for this for ages, and was wondering if there was anyway to disable Landscape in TF3D (and TF3D2) no matter what. I have a Fuze, and when i go to open a new message or program, then flick the keyboard open, the lag on TF3d landscape causes the SMS to open then TF3D to overlay over the top.
I never use TF3D in landscape, so i dont mind not having the feature.

Would really appreciate any help! Thanks!
