Hi Sergei,
Table sizes range from a few kb to 1mb. It makes now difference how big the tables are, the delay is about 40seconds every time a query is executed. I have tested this on other Vista machines and there is no noticable delay.
The data is all on the local machine.
BTW I have tried disabling firewall, MacAfee Etc with no difference. Our own technical support staff are at a loss.
Regards
