I usually do not have reason to use cursoradapters that incrementally fetch data, but my client wants to be able to scroll through a huge SQL table in a grid, so here I am.

In my form's dataenvironment I add a cursoradapter, and using the builder I give it my connection handle, query, max number of records to fetch at a time, select fetch remote data as needed, and left it pretty much like that. No updates will be done - this is strictly a lookup table.

I drop a grid on the form and it works well when just opening the form and scrolling through records - it appears to fetch incrementally nicely.

Now I go to close the form.

3 or 4 minutes later, it actually closes. My assumption is the cursoradapter is pulling the rest of the records for some reason before closing.

Keep in mind - during development my SQL data is out in internetland, so I do expect slow responses, but since I'm not telling the form to retrieve any more data or to update anything, I would expect closing the form to be fast/instant.

I've tried a couple of things in the form Unload event to close the cursor, tell the cursoradapter not to fetch data, etc but apparently I haven't hit the right combination to make it close in a reasonable amount of time.
