Thanks for your input. Based on your suggestion to use "xauth list", I verified that Fedora 2 is still using the MIT-MAGIC-COOKIE1 for authorization, so that is not the problem. Also, using xhost +localhost did not help. It is very likely that there is an incompatibility between the LessTif version used for the motifd binary and the LessTif shared libraries on my Fedora 2 system. I have another computer which is running RedHat 7.2 on which the CLM system works fine. On this RedHat machine the library libXm.so points to a LessTif/Motif1.2 library, while on the Fedora2 box it points to a library ending in .so.3.0.2, which I presume is Motif2.1. The libraries on both machines ending in .so.1.x all point to Motif1.2 libraries, and similarly those ending in .so.2.x point to Motif2.1 libraries. I don't know which library the binary is requesting. On the Fedora2 box, where CLM failed, the LessTif version is 93.36, while the builder of motifd (Raymond Toy) stated that he used 93.97. Perhaps a static build will solve the problem. Paul
