How to log/diagnose sending

// If you are using latest (modern) versions of EurekaLog - you can enable run-time debug mode:
// https://www.eurekalog.com/help/eurekalog/fix_runtime_issues.php
// Run your application with run-time mode enabled and find newly created run-time log file (.csl file).
// Open run-time log file and browse / search / filter / organize messages to find:
// "EurekaLog.Dialog" category and SendBugReport / SendBugReportInternal methods.
// "EurekaLog.Sending" category and EurekaLogSend function.
// The send log can be found inside these methods.

// Alternatively, you may manually log sending as shown below

// This code example will show you how to capture logging output from bug report sender
