> a. Dynamically link with the 3.1 libs and tell people to use XFree 3.1? Arrgh! Many of us still use 2.1.1 and don't want to switch. I would suggest two versions, both dynamically linked, against 2.1.1 and 3.1. If this is not possible, then perhaps option c) is best, although for those of us that don't have much memory, this will also be painful. elan
