Nancy,
Some things in the debug windows do track the datasession, and sometimes they change when even the mouse just hovers over different priv-DS forms.
From your later posts it looks like you had a bit of objcode oddities.
>I haven't missed the DODEFAULT. When I saw the behavior, that was my first thought, of course. But I _do_ execute the commands SET CONSOLE OFF and SET ECHO OFF. Would the datasession my watchpoints on SET('CONSOLE') and SET('ECHO') be different? I never mess with datasessions, never had a reason to fiddle with them since private ds and buffering, etc, work fine...
