I decided to finally give JRiver a try on my Mac. I downloaded version 19. When it started, it found an update, which I installed giving me the latest version. I restarted and tried to import my music off my NAS drive. Crash. I restarted and tried looking at the options. Crash. Crash. I let it do the import on its own, instead of pointing it to my NAS. It finds a few albums (I have over 1000) and then crashes. Crashed six times in five minutes before I gave up. Whats going on? I made no customizations, added no skins or plugins. Just using it as-is. Is it just not ready for prime time yet?
Side note: what is with the non-standard menus? Yours don't seem to properly close and they look kinda ugly. I think you are creating a window to simulate a menu for some reason (cross-platform?), but it is not good.
