Pages in designer not scrolling

Hi Team,

I have a glitch - in designer mode none of my pages scroll down (via mouse or pen), they simply glitch/repeat over the one spot. Only started a few days ago - I have been away so may have been earlier. It does scroll ok back up the page however, and the published site also scroll’s fine - just not in designer mode??

I have been working around it - if I scroll down and get the glitch the scroll bar appears briefly and I can manually scroll down the screen by mouse clicking and pulling down on that.

Does this make sense? Is anyone else experiencing the problem?



ps. happening on all my sites in my dashboard in designer mode, but here is the one I’m mostly working on if it helps…
