The event log bug has been fixed in Firmware 7.153 -see http://www.comfortforums.com/forum20/5042.html
The event log was designed for alarm and security events to avoid filling up the log with a lot of random events and having no room for important security events.
However there is an action Security > Save to Event Log where you can save an event index eg 01 to 256. You can embed the action in a response so when this runs it saves the event index into the log. You can use this to save any event eg counters etc which are called by respon se
