Random text highlighting when using Ctrl+N

when using Ctrl+N to create a new file in a folder, the first 6 or seven words of the second text file in the folder will highlight.
It will freeze typing input which is a double-edged sword - it will not erase the highlighted text but I cannot remain in my flow by using the keyboard shortcuts.
For the record, I’m on a dinosaur Lenovo running Windows 7 and a Scrivener Trial version (only used it for a couple days so far, thisclose to falling in love) version
