the only thing that will be affecting the Events status is code... an event is firing somewhere ...

Being a bore... let's check things off:

a) ThisWorkbook checked and clear of code ?

b) If a) is yes then... from native XL right click on tab in question and select View Code - is that clear of code ?

If neither a) nor b) are throwing up code then I would assume the Class Module is the cause... use Immediate window to ensure Events are enabled before doing anything... then with Class Module supposedly out of action repeat the copy & paste ... now check events status again, what is the status ?


Also be sure that whatever error handlers you have in place are ensuring Events are reset prior to exiting routine...
