column overflow at times --- any thoughts?

column overflow at times --- any thoughts?

[David Arnold]

Hans et al, Any thoughts on this?

We are using:

\setupcolumns
	[tolerance=stretch,
	balance=yes,
	blank=flexible,
	rule=off,
	distance=2.5em]

However, once in a while we get column overflow. See page 55 on:

http://msenux.redwoods.edu/IntAlgText/chapter0/chapter0.pdf

Are we doing this correctly? Any suggestions?

I do not understand what the problem is. At a first glance,
that page looks fine to me.

We've edited that page and the problem is gone. To see another  
example, consider page 61 of:

Can you try to manally add:

   \displaywidowpenalty0\brokenpenalty0

after the \startcolumns and see if it helps?

Taco,

Nice try, but didn't help.

The difficulty might be that Exercise #27 is in a textblock.

\beginquestion
\startquestion[ex:secqu.27]
$f(x)=\sqrt{x+5}$.

$\text{Domain}=[-5,\infty)=\{x:\,x\ge -5\}$

\column                   <--------------------Taco, inserting a

drawarrow p withcolor blue;
label.rt(btex $\tfx f$ etex, (10,f(10)) scaled u);

for y=0 step 1 until 3:
drawarrow ((y*y-5,y)--(0,y)) scaled u withcolor green;
endfor;
for y=4 step 1 until 10:
drawarrow ((10,y)--(0,y)) scaled u withcolor green;

pickup pencircle scaled 2pt;

If the \column break works out ok, then I am not going to spend
any more time on this, ok? No doubt there is a bug somewhere,
but without a minimal file it will be extremely hard to track
down anyway.

Cheers, taco

Thanks for trying, Taco. Appreciate the help.
