Just a WAG: sounds like the kind of behavior a table with a filter has...Could your cursor just be a filtered version of the table???

>When I edit a field and press the down arrow it takes 5 seconds until the next row is selected. The source is a parametized view showing always 16 records (1 per department). I believe I should set buffering to optamisitc table buffering. Should I use Transaction Processing? Where do you suggest I set all this? One last thing. A view of a child table must have a unique keyfield? I had wrongly set the foreignkey as the view's keyfield and when I edited a value I got an error message and all values in that column changed except for rows with nonzero values. So I created a keyfield with a candidate index for no purpose but to serve the view.
