Wsjt-x has random crashes. Currently running WIN10 on an i5 computer. Rig is Yaesu FTdx5000 with HRD as the interface. The crashes started when I upgraded to ver. 2.5.3 69fec. When I try to restart wsjt-x after a crash by clicking on the wsjt-x icon on the task bar, an error message is generated "a version of wsjt-x is already running". After a couple of system reboots and random crashes, I tried to see what was causing the problem. After a crash I started task manager. The offending program is “jt-9 wsjt-xx Slow Mode Decoder”. If that task is stopped, then wsjt-x can be restarted by clicking the task bar icon. What is causing the crashes? What does the offending program have to do with restart?
