[Typo3] Change pagetree width?

[Bart Veldhuizen]

Hi,

I've been searching for more than an hour but I can't figure this  
out: is there a setting that will allow the backend user to change  
the width of the pagetree part of the screen by simply dragging it  
wider? Since it's a frameset this should be possible from a HTML  
point of view and I have a vague memory of a Typo3 setting that would  
turn this on.

Maybe someone else has a better memory than I do :)

Many thanks!

Bart
