It seems that "Export Pngs" dosen't respect cancel button. It is funny when you cancel operation and yours home directory is full of pngs files :). I enclose patched source file(Pure version). But I would like to explain what I changed with commentary(IconDes::ExportPngs() - line 199):

void IconDes::ExportPngs()
{
    String dir = SelectDirectory();
    if(!dir.IsEmpty()) // <- Additional check
        for(int i = 0; i < GetCount(); i++)
            PNGEncoder().SaveFile(AppendFileName(dir, GetName(i) + ".png"), GetImage(i));
}

BTW, It is possible to export one certain icon instead of all in IconDes.
