Can you explain it briefly? I ask because the simple example > below seems to work as I'd expect VML.js:setStyle to work.
Because cssText is meant to set css on a CSS rule, not on a style. In IE, however, it works on styles (presumably accidently, and not very well). See the 2nd usage caveat on http://msdn.microsoft.com/en-us/library/ms533698(VS.85).aspx You could try node.cssText instead of node.style.cssText. Wouldn't surprise me if that would do the trick.
