I only hope that this has nothing to do with my rewrite of the menus (having different menus for the PdWindow and PatchWindows).
since test1 already includes your changes (afaict) and works well, i guess they're fine. i'm currently more worried that my attempt of restoring the "Pd help" entry is causing the issue and somehow interferes with the initialization: https://github.com/pure-data/pure-data/commit/eaa3fb53d287d15a07325e5f33a168...
... but same here: no idea why that's not an issue on my machine.
cheers, ben
