Hi Guys ’ every time I duplicate an HTML doc/file and then right-click / Ctrl-Click to Rename it just gets a blue background but doesn’t allow me to change the file name of the HTML doc.
I need to change different HTML DOCS \ is this a bug ’ it was never a problem before.
Possibly try left clicking, then right clicking the file? 
In Windows, click and select and then press F2, I did this several times today and it worked.
When you first click the file name the whole file name goes blue including the .html & looks like you can rename or overwrite this.
You have to then right click & choose rename which then just blue highlights the name part which you can then rename.
