i believe you can convert them in IconCool Editor...if that doesn´t work print-screening into paste always works! gl ;)
If you have Object Desktop you can use IconDeveloper to do it. That´s how I´ve been doing it for documentation I´m writing. <br /> <br />If you have IconDeveloper, double clicking on the .ICO will bring up IconDeveloper. Then right click on it and you can either copy to cilpboard or open it up in your editor. I usualy open it up in an editor (like Photoshop) because then it will come up as a .PNG which has the full transparency. <br /> <br />Hope this helps.
IrfanView can probably do it as well.
