Yeah, i am using proportinal fonts... funny i never noticed it before...

sorry, very sorry... i dont have time to do a patch at the mo, im off to the
Reading festival to get muddy tonight, so dont have much 'quality geek time'
available :)

I have however attached my code for scrollboxes, along with an old tree.c
which uses it, so people can have a peek at my code... in fact, most of what
I have done is in new units scrollbox.c/h (which lives in apps/recorder,
like the widgets.c), so a diff is not needed.

note that the copying routine is v. inefficient at the moment :)

let me know what u think,

> No, actually it has done that for quite some time. You're using
proportional fonts, right? The scroll code is not written to handle
proportional fonts, it works somewhat ok using something of a kludge. The
scroll code will be rewritten as we progress towards unifying the font code.
