Thanks for clarifications IOhannes!
I would really prefer to not declare anything with specific path references like this one with the Gem-0.93.3 folder. I understand it will induce problems if shared and if drives/sticks changes places, OS´s. The reason the versioned folder got there was due to the suggestion from Oliver to unzip all Gem.zip into the "extra" folder, which I did and got it there. I also tried to set path preferences (from menu - File-Preference-Path, also File-Preference-Startup, but it seems that neither of them are remembered after restart of Pd.
Will try to rename the versioned folder to just Gem.... instead of Gem-0.93.9 so to get rid of the dependecies. I hope it will work like that.
Guess I was happy that Gem finally started to work on this machine I am at, so didn´t see the fatalities of the versioned folder. (why is it anyway included in the zip-file if it causes this instabilties?)
All the best!
