Internet Explorer doesn't support overflow for elements when their opacity setting is anything other than 100%. If you run into this problem, using dojo.xml.htmlUtil.setOpacity(node, 1) won't fix it since we translate any value greater than or equal to 1 as 0.999999 (99.9999%). To get around this problem, call dojo.xml.htmlUtil.clearOpacity(node) or supply setOpacity with an optional 3rd argument of true to use no normalization of the opacity value.
On IE 6.0, I experienced problems with fading text using the dojo.graphics.htmlEffects.* methods: Unless the background-property on these text-elements was set to some non-transparent value, the text rendering was not smooth (See examples).
Also on IE 6.0, only the variable "window" can be used to connect events (I suspect others may be only copies). So if you want to find out the associated window object from an element or a document, please use dojo.html.getElementWindow or dojo.html.getDocumentWindow. In addition, newly introduced dojo.global() can also be used to connect events.

Fading to black with background-property not set (or set to transparent)
ading to black with background-property set to white (or some other color)
