thanks hans. I played a little bit more, tried other nightly builds and the problem persists. I'm thinking it may be related to my os state.
I started reading about compiling pd-extended, it might be not too difficult for me to try, but I was wondering...
what if i want to build a "stand alone" executable, I mean not linked to system libraries, so that it can be even put on a usb stick and carried anywhere (on different distributions, maybe)? Is the tarball option in the make system just doing this? Is this idea a nonsense?
The recent files are stored in ~/.config/pd-extended. I suppose all the
config files should go there.
