After submitting query to ChatGPT, can't scroll at all

I am using ChatGPT 4 in Vivaldi in OS X 14.4:

Vivaldi 6.6.3271.53 (Stable channel) (x86_64)

After I submit a query into ChatGPT 4 and press enter, I get a response but can’t scroll up or down if the response is long. When I click on the scroll bar on the right, it is not responsive. Pressing the up or down arrows on the keyboard does not result in any response. The only remedy is to hold down shift and force refresh the page to be able to scroll up or down to read the response to the query that was submitted.

Has anybody managed to find a workaround for this phenomenon?


See related bug discussion by searching for “Is anyone else suddenly lacking keyboard scrolling (PGUP/PGDN/HOME/END)?” (I can’t post direct links yet).

I was never able to find a fix and cancelled my subscription. I doubt OpenAI is reading these messages as nothing has been done about the many complaints on this issue.
