Suddenly, yesterday afternoon (3/12/22) Smath stopped running. If you launch the program, the logon logo is displayed then nothing. It doesn't show up as a running program. Running TaskManager then launching SMath, I can see SMath pop up in the list of processes then in the status column there is briefly displayed "suspended" then the process disappears from the list. I uninstalled the program and reinstalled it but no joy. Can others run the program? Could it be restricted because of Russia's war on Ukraine? I've turned off Norton and MalwareBytes but that didn't help?

Solved the problem. Apparently, a file was corrupted in the SMath folder. Uninstalling the program did not remove all of the files. Using the Event viewer, I determined that the core program Solver was faulting. After checking the Windows system files which didn't help. I uninstalled Smath then blew away the entire SMath program folder to delete the handful of files not removed and reinstalled the program to solve the problem.
