I have the same problem.
1. The operating system WIN10. There are workflow icons on the desktop.
2. With the latest update of Pix 1.8.8.4, when you try to open the saved workflow icons, the program goes into reconfiguration and WIN10 restarts the computer.
3. After the reboot, everything works. I am watching the version of Pix 1.8.8.3, which offers an update.
4. The first automatic update of 6 files is successful. Saved workflow icons open and everything works.
5. I am watching the version of Pix 1.8.8.4, which offers an update. If you agree to the second update, then after the update all problems are repeated.
Sincerely, Dmitri.
