Drop and Re-create table does not show columns in the alias drop down

When I drop and re-create a table with new column names it does not show that column names when selecting using an alias name for that table. That new column does not show in the drop down box, even when I re-connect or start a new instance or connection.

Are we talking about seeing your new information in the Type-Ahead box within Toad's Editor? I wonder if this particular option in Toad helps... worked for me...

Hi Gary:
Thank you for your response, I am on 13.1.1.5 and I do not see the 'Use Background Session' option.
But I do see that you have you have unchecked 'Cache Results' which I am going to uncheck and see if it helps.
Thank you!
