It's all sorted now.

It turned out to be a pointer that I initialised wrong in another function
somewhere (that loads images to the frame buffer). I don't have a clue why
it affected all the print streams but there you go, bizarre.

Anyway, cheers to Stuart who took the time to look through the code and give
me some nice pointers( that's pointers as in tips, not pointers as in the
things that hold memory add......ah forget it. ;o) )
