title: BigQuery practically unsuable
body: <p>BigQuery's browser interface is practically unusable. 
  If I run a query and save it as a table (Enable Options) and then immediately run a query on the new table, bigquery always throws "Error: Query cannot refer to the destination table.". I have to refresh the page to avoid this error. </p>
  
  <p>I just ran a bunch of queries like:
  1) Used "Enable Option" to create a Total_A_Table:
  Select A, "Table1" as Source from Table1</p>
  
  <p>2) Append to Total_A_Table
  Select A, "Table2" as Source from Table2</p>
  
  <p>3) Append to Total_A_Table
  Select A, "Table3" as Source from Table3</p>
  
  <p>4) Append to Total_A_Table
  Select A, "Table4" as Source from Table4</p>
  
  <p>It keeps showing me results from Step 2 on Step 3 &amp; Step 4. To make it work correctly, I have to refresh the page after each query! </p>
