Exporting problem with 2025 Premier Elements.

Thank you.  Just before I got your response I noticed a grey bar above my timeline. Now I know what it does. I really wish someone would submit a tutorial with just picture on the screen and then descibe what each bar, widget, object etc. is for and tells us the name of that thing and why we need to operate it.  It took me a long time to figure out the scissor won't work if you don't have the cursor at just the right spot.  Same with the Transitions -can't click on the box, must be on the words.  Thank you again.
