When trying to use F4 to desc a table in the editor, the following error is given:
"Toad for Oracle had encountered a problems. We are sorry for the inconvenience"
There is a check box to restart Toad. This was not always an issue and only resently started occuring.
Reset the settings directory and files to default values.
1. Exit Toad
2. Go to (Windows 7, Toad 11.6) c:\Users\<personal folder>\App Data\Roaming\Quest Software\Toad for Oracle
3. Find the 11.6 folder (example Toad 11.6) and rename that folder, i.e. Toad for Oracle\11.6_OLD
4. Start Toad again, connect, and test for the issue.
