Hi,

I'm having major problems, trying to put a transparent png as the Icon for a toolbar item, for some reason it makes the background white (this also seems to happen for a Canvas background as well)..

I've looked through the Language Reference and cannot see any option there, I've also tried *.gif and *.psd's, but all have the same effect. The only workaround I can see is to take a screen shot of the app, then use the toolbar background colour as the background for my icons.

For MacOS X toolbar icons, I have found it simpler to use an .icns file and set the icon using HIToolbarItemSetIconRef. I explain how to do so in chapter 3 of my book on declares <http://www.declareSub.com/>. MacOS X includes a utility, tiff2icns, that will convert TIFF images to .icns files.
