Ed, that fixed did indeed work for the parallax.
As posted in the other thread about sticky headers, this same fix also seemed to fix the sticky header issue in Chrome when using a revolution slider. With the only issue being that the sticky header is now spaced under the top admin panel while I am logged in and this occurs on all pages.
I am pleased with the parallax working and the top admin panel issue is more of an annoyance, but it doesn’t occur without the new fix. Just fyi. Thanks
