I opened PI and was notified that the latest math bugfix was available, which I downloaded. I continued working in PI. When I closed PI, it asked if I wanted to install the update. I unchecked restart PI and said yes. Nothing! I tried to restart PI, but it would not come up. Opening the task manager, I saw PI running in background and killed the process. I restarted PI and it indicated the bugfix was ready for download again. I downloaded it again and closed PI. This time I said restart PI and everything worked as expected. Easy work around, but should be fixed.
Regards,
Charlie
