I want to resurrect this issue as it has remained unsolved and it is really bothersome. In a long query (let's say returning 20000 rows) the horizontal and vertical scroll bars are inoperable. I have to wait until the query finishes to scroll the results. This is not what V14 did. Secondly, in a long query, I get no response when I click on the red hand in order to stop the query. I have set the Oracle preferences to Multi-session, and multiple connections are allowed.
Is there a difference between installing this for one user vs. all users on the machine. This is a Lenovo T series laptop running Windows 11.
