How to disable spinning wheel when writing queries

Hi
TOAD 12.5.
When I am writing queries as soon I am typing an alias a spinning wheel is appearing (looks like trying to retrieve the column names from the database) and I am unable to type ahead, and at times it even takes a few minutes for the spinning wheel to settle. In worst case the screen freezes. Is there a way to disable the spinning wheel - as I do not require any assistance with the column names when writing queries in the queryWindow
Thanks in advance
Regards
Sanjay

You can disable Code Insight in Toad's Options. I'm using Toad 13.2 as a reference so the exact option name may differ in 12.5, but in Options go to the "Editor | Code Assist" page. Disable "Auto invoke" for Code Insight or whatever the option is named in 12.5.
