RE: [Dynapi-Help] Event Problems - dyndoc.id

[Guangyi Wu <gua...@al...>]

I used the dynapi.gui.label.html in package posted by Dan. There is a table
in the layer, and a font in the td. I was surprised to see the e.srcElement
pointing to FONT tag in the debugger by onmousedown event.

AFAIK, src should refer the layer most near bottom to start DYNAPI event
bubbling. In IE, the "this" in EventMethod() should be this phisical layer,
because it is registered in captureMouseEvents(). If it is, this.lyrobj
should be a better start layer than tis.lyrobj.dyndoc.

Are there other exceptions I ignored?
