Thanks a lot for your help Enrico, unfortunately I've already installed the cygwin tetex-extra package and I already have the acronym.sty package in the following location: \usr\share\texmf\tex\latex\acronym\acronym.sty but for some reason it seems lyx is not able to find it. Actually in: c:\Documents and Settings\<my user name>\.lyx\packages.lst I have the following list of packages: array babel color geometry longtable varioref graphicx but not the acronym package. I tried to add it myself (just typing it there, a bit naive, I know) but after running reconfigure it was obviously removed. Do you have any other suggestion on how to solve this problem? Any help or workaround would be very appreciated. Thanks a lot Francesco
