Either the bug is fixed or there is a subtle difference between our installations, but I do not get an error. Versions: This is pdfTeX, Version 3.1415926-1.50.0-alpha-20080414 ConTeXt ver: 2009.06.03 11:48 MKII This is MetaPost, version 1.202
I also don't see the problem with a newer installation. In particular: Creator: ConTeXt - 2009.06.04 22:20 Producer: pdfTeX-1.40.9 (with texlive2008) But I also noticed that the vertical spacing is different from what ConTeXt 2008.10.31 produces (part of Debian texlive2007). The vadjust problem is very sensitive to the vertical spacing, so a change in vertical spacing might be hiding the problem. I'll use the newer ConTeXt/pdftex setup for the full math textbook (of which lumping.tex is a chapter). That should be a good test of whether the vadjust problem is still there. By the way, is it worth my tracking down the difference in the vertical spacing? Or is that an expected change between 2008.10.31 and 2009.06.04? -Sanjoy `Until lions have their historians, tales of the hunt shall always glorify the hunters.' --African Proverb
