Oracle SQL Developer - Query results window with grid missing

I've just made the switch from MS sql server to Oracle. The query tool I am using is Oracle SQL Developer. The problem I am having is that I cannot get the query results window to stick around. The query results window being the Grid view for the results. It seems to show up arbitrarily when I open a new "sql worksheet". But not always. Then once I run a query, it disappears the next time I run one.

Can anyone point me to a consistent way to leave this results grid active? Thanks so much.

How do I edit query results in SQL Developer?

Follow these steps to edit/delete rows from a table in Oracle SQL Developer: Expand connections, and select your database connection. Expand the Tables, remove any filters if applied. Just click on the table name you want to edit, or right-click and select Edit.

ok guys. figured it out. I was hitting F5 (as in MSSQL query analyzer) to run the query. That is "run script" in this client. F9 or Ctrl + Enter get me to the query results grid view. Hopefully this helps someone else in the future.
