SQL Complete's Auto suggest stops working sometimes

[Thenrich]

Sometimes I am working in a query window and suddenly SQL Complete's auto suggest stops working. It stops showing table names from the database. The query in the window runs fine. If I open a new query window and copy everything from the bad window to the new window, auto suggest works. I have tried resetting and refreshing the cache many times. Once SQL Complete behaves badly, I have to close the query window and use a new one.
