I had recently upgraded to SW2010 Premium SP 2.1 (Win XP Pro x64), and the mouse gesture does not appear to be active. Are there are reported issues with mouse gestures and SW 2010 SP 2.1 or x64 Windows?

The mouse gestures is enabled in SW (see attached), so am I overlooking a setting in Windows? The buttons are switched as I am using the mouse left-handed. I tried both LMB and RMB and SW responses as it did before upgrading to SW2010. No, I cannot update to a later service pack until I am on maintenance again.
