Problem creating new topic in forum with Chrome

I have been using Firefox to access this forum, but recently found that it uses too much memory, so I started doing it from Chrome.

In Chrome, when I click New Topic, say under the view of Usage, I initially get the editing area at the bottom of the browser, but then more topics in Usage get refreshed in and the editing area gets pushed down further, as I scroll down to the edit area, more topics get refreshed in and the edit area get pushed further down. So I can not really get to the edit area.

Aren’t anyone having this problem?

I also use chrome on win 10 but never faced this issue.

I am on Mac Majove
