It could be Toad or it could be the Oracle client.
Please connect to the database that you have the problem with, then in Toad, go to Help -> Support Bundle. That will collect data about your environment.
You can email it to me: John.Dorlon@quest.com.
Also please send me your user files folder. This is where your Toad settings are stored. To find that:
- Go to Main Menu -> View -> Toad Options.
- Along the left side, click Options -> General
(or, in Toad 17.0 or newer, Options -> Files and Folders -> App Folders) - Click the "Open Folder" button on the right. A Windows Explorer window will open.
- Close Toad before you continue.
- In Explorer, Zip up the "User Files" folder.
- email it to me.
Hopefully then I will be able to repeat the problem and tell you what you can do differently to avoid it, or if there is a bug I can fix it.
Thank you.
