Alice 3.3.1.2 Crashing often

[espruillRMSEL]

Hello all....I have several students using Alice 3.3.1.2 on Dell Optiplex 3050 PCs running Linux. For some of my users, Alice works consistently with no problems. For other users, it crashes often, so frequently that it makes it hard for them to make any progress. I've had students save super frequently, almost every time they make any change, even rotating an object. This seems to help, but I'd love to know if there are any other solutions to fix the crashing problem. Thanks!
