What version of Premiere Elements on Windows 7 (assumed 64 bit)?
If you have Premiere Elements 13/13.1, are you referring to the following look in the Edit area monitor when the Timeline Indicator is at the end of the last item on the Timeline? If so, that is Adobe's way of displaying the end of the Timeline content in version 13/13.1.
That view should not display in the playback of the export using your computer player or TV player.
Please consider and supply more details.
