Hadn't seen the last comment though the thread died or derailed.

Though sometimes someone shows up who hadn't read the original one (and repeating something may get it added as a feature later)

Don't really follow you.

You create selections. The selection only loops when you have loop playback enabled.

So, you don't want to make a selection?

You can use the left right arrow keys to move the edit cursor position if the mouse is too difficult for you to use on the cursor.

Try this to see if it does what youn want
In preferences/editing- uncheck Collapse root when no Time selection is present
Then move cursor to a any position on TL

John,
the "collapse loop region when no time selection is present" option appears to have been removed for Movie Studio Platinum 12.0 due to a decision made by the developers. If you'd like to see it again, or if you have other suggestions for our applications, please visit the product suggestion page.
The italics text is from the SCS Support answer to my query on this.

Make it a habit of making the loop region zero. With the cursor anywhere on the timeline press the "i" and "o" keys (In and Out) That will put the start and end of the loop region at the same point on the timeline.

AND ... make it a habit of checking to see if the "Render loop region" box is checked before each render.

Either one will work but get in the habit of doing both for backup.
