The x86-64 version has problems with some of the Gorilla Icons in the new builds. It loads the images but it doesn't make the exchange.
I don't know if I understood correctly, with the version compiled by me on AROS One 64 v11, swapping Icon "Gorilla Icons" with "DualPNG Icon" and vice versa works fine, I attach small video (watch it from PC)
