If you're looking to try and extend the timeout?
Don't have access here (boo) but can sort of recall something in the generic setup that might do it.
Failing that, write a simple query that has the * as the field (so returns all fields) and no selection criteria. This then allows you to check the properties of the query and change the timout to 0 (zero), essentially turning off the timout on that query.
Never know, that might work, and it'll still give table like access to the table, just without the risk of someone changing the fundemental table design (probably a good idea).
Cheers.
