[WB20] How to trap when a user closes or leaves a page (1 reply)

Hello All:
I'm using WebDev 20, and I need to do a small processing before the user closes or leaves the current page. I tried putting that process in the Closing of PAGE_Test event, but it seems this is not always triggered... I think if user clicks on a button that opens another page, then this event doesn't happen (I'm not sure if this is exactly the case, but for sure this event not always happens...).

Is there any other way to accomplish this task?

Thanks in advance for your help.

Regards;
Michael R.
