Hello,
Since this morning, when our browsers (chrome) updated to version 32.0.1700.76 m, we are experienced a problem with the RadContextMenu placement when the page is scrolled down (pic2.png).
Checking for possible errors we found the following:
"body.scrollTop is deprecated in strict mode. Please use 'documentElement.scrollTop' if in strict mode and 'body.scrollTop' only if in quirks mode."
We checked in your demo page and there is the same problem. We tested it in other browsers and it's fine...
Thanks,
Rodrigo
