Tired that today and just again now. Doesn't do anything. Pressing and holding the menu soft key brings up a search function but nothing with the soft return....

For most U.S. phones, the carrier had to deliver an update to enable the multi-Window feature. Not for sure if the Tellus model qualifies as International but I suspect it doesn't.
To see if there's an update available you can go into settings and check for updates.
