My website is: http://impactpwr.com.previewdns.com/
On the home page if you hover over Wireless Solutions in the top menu the drop down menu appears correctly but you cannot get your mouse to the next level such as Wireless Solutions>GPS Solution>OEM GPS Antennas
Yet it works correctly on a static page such as http://impactpwr.com.previewdns.com/customer-support/literature-requests/
I slowed down the speed of the slider but the issue is the same. Not sure but it seems like it worked before the lates upgrade.
Thanks for the beautiful/flexible theme.
