@mac84tv Hmm, weird. It works on older systems, and newer systems. MacTCP shouldn't make any difference since it only uses AppleTalk.
If you have spare time (huge ask), I could get debug information if you (1) installed MacsBug (2) ran the version with debug symbols (in BaroNet:landisk:Junk Bin), and when it crashes run “sc7" in macsbug and take a picture 🙇♂️
