I got it now!, what am I so happy about?, I was creating a cursor from the grid's record source with a select statement. Anyway, creating a session object for the cursor solved it just like you mentioned, thanks.

>>I tried do duplicate it by having a form with a grid, generating the cursor and calling the report from the double click event of the grid but had no luck, except if I explicitly selected another table but that's just asking for it :), but hey, no complaints, why am I even trying to put bugs in my code? <g>. Perhaps it's something else we're missing.
