@b3m2a1 Yes, I am sure you did try to make reproducible example. These things can be very hard if they happen at random. I know, I have same problem with Maple. But there it is not the GUI, it is the kernel which keeps crashing and hanging. For many years this is still not solved and impossible to reproduce since it happens at random times and different location each time. Main problem is that CAS software is becoming too complex, the companies that make it are unable to fix all the bugs in it!
