Tux Paint version 0.9.21 is installed in a lab and a mobile lab. It is crashing for many students, but not all. Deleting the .fontconfig file as suggested on the website did not work. It is definitely an account issue and not the particular install on the computer because I can log on as a different student on the same computer and it runs just fine. I have angry staff and anxious student's if anyone has other options to try.
