It might help if you could give specific problems you are having. It's true that I have had problems over the years with certain FOSS (free and open source) software . But at the same time, there have been just as many times that I have had software run like a top! Windows does me the same way,.....so it's not FOSS being somehow inferior to what mikkysoft does. Just happens.
Some times it's my hardware and computer that is causing the problems with the software.
BTW ....that other thread that was referenced really didn't seem all that helpful,..did it?
