Always good to say what version of Premiere Elements you are using and on what computer operating system it is running.
If I knew, I would post a screenshot to point out what I believe is the cause of your issue.
1. Do you have the gray tabs of the Work Area Bar set so that they span the Timeline content from start to just the end of the content?
2. If you hit the End key to get to the end of what you see as the end of the Timeline content, does the Timeline Indicator go beyond that end. If so, besides checking the Work Area Bar gray tabs, look for leftover in the tracks. Typically they present a thin vertical black lines scattered in the track contents. Delete them.
Please review the above and then let us know if any of that worked for you.
Thank you Mr. Romano,
I found a gray area at the end of my project that I was able to remove
which gave me the 7 minutes I was looking for.
Great help. Thanks for the super quick reply.
Thanks for the great news that the cause of the problem was found. Good work.
The follow up was much appreciated.
