ugh i didn't get notified of this. what you mean deleting user directories?
I'm aware re-installing doesn't delete/replace user data or some of the settings.. I did go from completely clean osx copy though so should be nothing else bugging it.
I don't see a .fritzing or any other in my home directory or documents.. i've tried searching and deleting.
It's sad cause without the ability to search for parts it pretty much renders fritzing useless. I spend more time looking for resistors then actually building things 
This is not the first version i've had issues with. I switching to circuits.io for a while hoping it would get fixed in an udpate/upgrade but to no avail :(.
Fritzing has been awesome for teaching and getting parts done quickly. I've donated in the past and if I can help debug I'll gladly spend the time but as is I can't continue using it.
