I was unable to cancel the data fetch on a Described Table with ESC, using this shortcut has no effect. If I try to close the Desribe window it says “Data tab fetch in progress. Wait for it to finish or use the cancel button to cancel it”. Where is the cancel button?
It might be important that I used a VPN connection, and the table contains CLOB, BLOB columns. I pressed the Ctrl+End button accidentally and I tried to cancel the fetch, with no success. After a while I tried to close the connection from the toolbar then I got an “List index out of bounds (79).” AV.
