Fritzing now crashes on my Pi (running Raspbian O/S)

Well , I thought I had been experimenting with other software so much that the O/S got corrupt. It finally would not open any of my software Qt Creator , Fritzing and others .Sooo I reinstalled O/S and got latest version of everything ,including O/S. Everything works again so far. Maybe when I was trying out the OPENGLES stuff it started the crashing process. A new desktop PIXEL is out and who knows how well it handles the graphics. Also my own code can go crazy some days. Don't know why all this can be very bad for an O/S in development.
