SQL - "Save results as CSV" - use comma instead of Semi-Colon

Hey, i need to export a query result to a CSV, but i get a semi-colon as a delimiter.
I went to:

Tools - Options - Query Results - SQL Server - Results to Text

and set

Output format: Custom delimiter  
Custom delimiter: ,

and i still get the semicolon. when i return to the options, the original configuration is set.

I'm using MS SQL Management Studio 2008.

Thanx for the help

Solution

This one of the options that needs you to close that query window and open a new one before it takes effect.
