| Performance problem with QODBC Version 8 |

I use QODBC with MS Access and some Make-Table queries. Essentially I make a copy of the QODBC table. But this new version is very very slow. For example the BillExpenseLine table is 21,000 rows. It used to take a couple minutes to create. Now it takes forever, like an 30 minutes or more.
Here is the SQL code access uses:
SELECT BillExpenseLine.*, Now() AS ExportDate INTO BillExpenseLine IN 'Q:\Data\QB_Raw_Data.mdb'
FROM BillExpenseLine;
I have optimizer on in the ODBC connection

I changed the optimizer setting from "The start of every query" to "The start of every new connection with Load Update". I also freed up some space on my C: drive, I had 1.1GB free, now I have about 3GB. Now it works pretty good. It does the BillExpenseLine table in about 10-15 seconds.
