Not sure if this is me?

Open editor - New HTML Page - opens as HTML5

Select Code - button at top is on HTML4.

Change to HTML5.

Close programme and open again - goes back to HTML4.

I have done further checks and now think that this is how it works.

Opened a project.

Code Button - HTML4. But when you open a saved HTML5 doc the button goes to HTML5.

So all looking good.
