Hi, Toad has been working fine, for years. Then all of a sudden, randomly, certain queries are taking 10 - 15 seconds to return. I can run the same query 5 times, and 2 out of 5 return instantly, and the other 3 take enough time that the software says "Not Responding".
This is true for browsing tables also. Even selecting from DUAL or from V$SESSION has the same behavior.
Has anyone else had this happen? I was running version 10, and upgraded to 13.3, and the behavior persists.......
