Two questions - where are the log files located & why

[Jack Efferson]

Hello, I have installed Pira running in 4 instances to monitor for silence over 4 different sources and it works great! Thank you for this very useful program Jan!!
I do however have two questions:
1. One instances only monitors the audio from my USB audio adapter when the Mixer panel is open. When Mixer is open all works well. Close Mixer and Pira shows silence and sends alarms. All other 3 instances have no problems even after reboots.
2. I see the options to log events, but I am unable to locate the log files. Could you point me in their direction?
Thanks for your great products, I love my P275!
