thanks Wolfgang for your advice and sorry for being so verbose, but since the margins are "included" in the problem I decided to put my layout there too. I made your suggested changes and unfortunately it doesnt work, but being a bit surprised by the margins I printed a copy of the page and.... still worse... It semms that the first frame is good aligned to the specified margin, and it is the rest of the text that gets more than 5mm extra space at the right margin and about 2 mm less in the left margin. I think the printer is a bit involved too, but since in the pdf we can see this protruding I think there must be something strange to get this outcome. The papers are for my fellows, so it is not critical if it stays so, but since I'm trying to learn a bit more to use context, it annoys me that I don't get to understand some problems... thanks again for taking time
