Windows MIDI Services Settings App
Type of bug
Application Crash
Steps to reproduce
Cant reproduce.
Was testing if the new KB update was enabled by creating a new LoopMidi port and seeing if it appeared in the Midi Scratchpad feature in the MidiSettings.exe app. It didnt.
Used the Restart Midi Services button in MidiSettings.exe
Console opened with the two messages about restarting the service. Then the settings app crashed (I have Qt debugger installed, so it offered to start debugging, which I declined).
Restarted the MidiSettings.exe app.
Used the Restart Midi Service button. New loopMidi ports are available, no crash.
Info from Reliability Monitor below. I dont find any dmp files in C:\Windows folders for this.
