Files won't open

I recently found that a file fails to open in windows explorer if the pathname contains a comma and the Steinberg Hub is open. Opening the file from the Steinberg Hub itself works correctly, as does opening it when the hub is not running. The comma seems to parse the pathname and I get the following error messages.

Old news, I’m afraid:

Sorry I missed that. I did look!
