Outlook 2003 Not Closing Properly With Bd

Installed Bitdefender 2010 Internet Security recently but found that Outlook will not close properly (leaves an icon on the task bar at the bottom of the screen). If I run Outlook again then I don't get the BD taskbar. If I go into Tak Manager I see that the Outlook process is still running. If I close this then I can start Outlook up again with no problem.


I have another user on my PC and Outlook runs and closed fine with them!


Maybe because I installed BD under my account?


Any help/ideas please - have tried re-installing but no difference.
