[NTG-context] Problem with backgrounds and page breaks

2005-01-10 Thread Matthias Weber 
Hello,
when using text background colors in enumerations, I run into a problem
whenever the enumeration appears on the beginning of a page: Then,
the background extends over some part (sometimes all) of the previous 
page.

I can manually correct this by putting a \break just before the 
enumeration, but this
is a little tedious, as I am frequently reformatting the document. 
Below is a small example.

Thanks for any help!

that way a pagebreak is forced when less than three lines are left

Thanks, Hans, this fixes it most of the time. But the problem still 
occurs with  one new line
less. (Example again at the bottom) :(

Thanks, that brings it down to two problematic cases in a 400 page 
document,
and I can live with that.

in your case the testpage should test for 3 lines, because you have 
5pt margin +  a blank before it

\testpage[3]
actually the best solution is when i start introducing special 
background options (no time for that now, o for the moment use the 
testpage); that way i can  hook it in the righ tplace
