Why should I put it at Workbook_BeforeClose? If its closed the timer will be killed anyway?

The second assumption is pretty right in my case because I have coded to close the application, not only the workbook, so if its leaved to work on another workbook, both are gonna be closed. But that was intentional. (Is it a ditactorial code or what? )

You know, sometimes I just feel I kinda hate the user and start punishing he/she
. (just kidding)
