debug-detailed gave no additional useful information....for example, with web calls:

2022-09-05 21:26:59 (1) func:PrikaziProdNal
2022-09-05 21:27:50 (1) CallHal("CallTXIdleTasks")
2022-09-05 21:27:54 (1) MM speed min: 0 ms, max: 1ms
2022-09-05 21:27:54 (1) MM speed last minute number of OS allocations: 4 average speed 0ms
2022-09-05 21:27:59 (1) /THREAD(23) failed to create file web_sessions.log E:\Standard ERP Server is current directory
2022-09-05 21:28:00 (1) func:PrikaziProdNal
2022-09-05 21:28:00 (1) /THREAD(23) windows error: The operation completed successfully.

With printing, the log looks exactly the same as at default verbosity

"Updating Web Calls...." has been active all along.
