Willi,
The artefacts occur in both versions of Context tested.
I don't see those artifacts. I'm using Ubuntu GNU/Linux and xpdf 3.0 as the viewer. I tried two tests: 1. % pdfTeX Version 3.141592-1.40.0 (Web2C 7.5.6) % ConTeXt ver: 2007.01.12 15:56 MKII and I downgraded the pdftex temporarily (and remade formats): 2. % pdfeTeX Version 3.141592-1.30.3-2.2 (Web2c 7.5.5) % ConTeXt ver: 2007.01.12 15:56 MKII Do you want to send me your PDF file and I can view it here with xpdf to see whether the artifacts are specific to Windows acroread? Actually I'll send you my pdf file (off-list) and you can try the same experiment in reverse. But I do get the same errors that Peter found: ! Font \*16.7ptrmitss*=ec-lmri10 at 16.7pt not loaded: Not enough room left. etc. (but if I type 'R', it runs without stopping and the pdf file views fine). Alas the dvi (and ps) file shows complete boxes, which is incorrect. -Sanjoy `Not all those who wander are lost.' (J.R.R. Tolkien)
