thank you for the reply. a note to anyone else trying this: it can be a good idea to put this setting in the theme.rc instead of the popup.rc. that did the trick for me. the fact that i was unable to get the desired result by simply editing the popup.rc was the reason that i was dissatisfied with the thread being locked: the answer which i was given did not produce the desired results.

but once again, thank you for the answer.
