Hi Philip,
If the GraphFiles bit in the Distribute object under the NodeConfig object in the directory volume is set, all pwg-files in $pwrp_exe will be included in the distribution package. It is set by default, so I guess the problem is that the pwg-files are not copied from $pwrp_pop to $pwrp_exe in the development environment. If there is an XttGraph object for the pwg-file this should be done when the node is built. Otherwise you can click on the build button in the Ge editor to copy the file. It's also possible to configure the copying by creating BuildDirectory and BuildCopy objects in the directory volume.
