I can virtually count on the program hanging if, after ripping a CD, I don't close the little box that appears saying the rip is complete before putting another CD in the drawer.
Yes, I've had this problem and I eventually trained myself and my wife not to do that. (as in "Doctor, it hurts when I do this.")
As of late I've found a certain lack of enthusiasm on J River's part w/r/t bug hunting. You can tell them a bug reproduces on three different machines and they'll tell you that doesn't prove it's their problem rather than put any real effort into helping you find the cause.
Admittedly, it very well may not be their problem but too often the burden of proof is 100% on the customer. Maybe if I had source code I could debug I could deal with that but I don't.
Should I just be happy I have a forum to report bugs in? Probably not, when reporting bugs doesn't have any effect (and in fact your told, in effect, it's your own fault). Maybe I should just count my blessings that I get to debug countless beta releases for J River? Maybe I can console myself that I "only" paid $25 for this software? You get what you pay for, right?
I loved MJ version 7 under Win98. Version 8 has been a bit of a disappointment for me due to quality problems even after upgrading to WinXP. I'm hoping MC 9 is a fair bit better and the upgrade is flawless (none of this try uninstall, reinstall, try reinstall windows crap). Hopefully the version 9 install will know how to clean up any turds from previous versions that can cause problems.
http://www.pcmag.com/article2/0,4149,804997,00.aspPC Magazine's review of jukeboxes even mentioned glitches when using MJ 8.
Some technically savvy people have the know how and the patience to work around the glitches they encounter using MJ but I suspect a fair amount simply frown and move on to the next jukebox vendor.
