StampAll displaying pop-ups

I am wondering if anyone else has experienced this - whenever I run any lotusscript code which contains a stampall function, the function is resulting in a pop-up indicating the name of the field which is being stamped -regardless of whether debug is on or not.

I am experiencing this in custom apps, as well as in the mailfile - when setting a followup flag for example.

Has anyone else experienced this - is there a way to stop it?
