To be quite honestthough I appreciate your generosity hereit really irritates me that you release your icons as 512px sets tucked away in dmg's accessible only to mac users. The "windows" zip in comparison has a piddly number of icon sizes, the max being 128px. You realize that the days of XP are over, right? and that Vista and 7 use 256px RGB/A icons to scale from, right?
I see this as being either snobbish, disrespectful to your users, or quite uninformed.
Hmm its not done intentionally, the software we use outputs the windows version of the icon at 128px max. If we were to get the 256 size we would have to build each icon manually and that's tedious. Hopefully when iconBuilder is upgraded to support the 256 icon size for windows we can upgrade. So it is not that we favor Mac users over Windows users we are just limited right now buy the tools we use. We sincerely apologize for any inconvenience caused.
