The StillOpen Event message is sent even when there are no workbooks to report

[AndyLockhartHSBC]

For example the following messages are sent:
2023-07-18 17:59:32,269 [1] INFO XLMonCOMAddin.XLMonCOMAddin - Sending : {"Evt":"StillOpen","Time":"2023-07-18T16:59:32","SID":"3ddaca09-7610-4446-95c5-a535cf504fe6","UsrNm":"xxxxxx","MchNm":"yyyyy","IP":"zzzzz","MchUpTime":37581593,"XLUpTime":4816}
2023-07-18 17:59:42,860 [1] INFO XLMonCOMAddin.XLMonCOMAddin - Starting Disconnection. Doing final write of XLS Times and Loaded XLL Add-Ins
2023-07-18 17:59:42,860 [1] INFO XLMonCOMAddin.XLMonCOMAddin - Sending : {"Evt":"StillOpen","Time":"2023-07-18T16:59:42","SID":"3ddaca09-7610-4446-95c5-a535cf504fe6","UsrNm":"xxxxxx","MchNm":"yyyyy","IP":"zzzzz","MchUpTime":37592187,"XLUpTime":15407}

There is no need to send this message if it's empty. The same goes for LoadAddins
