  Hi everybody,
 Sorry for the silly question, but i have an annoying problem on custom
 icon visualization.
 The background of them appear correctly transparent in firefox, instead
 in explorer it appear as "lightgrey" (as shown in the image attached)
 The png have been created with 
Paint.NET 3.0...
 Does anyone had the same problem? How do you solve it?
 Thank you!!

IE 6 and earlier don't know about alpha-transparent PNGs. That's the
most annoying thing web designers hate about Microsoft and its browser.
In IE7 it should work.
If you don't need full transparency (meaning semi-transparent pixels)
but jost 100% or 0% transparency, then that you can do. I never used
that program, but i guess it should have an option for this.
