Sorry Jim, but I think you've missed the point here totally.
MC is the only app that I'm having problems with and I would'nt dream of having to go through your suggestion of stripping, updating etc for just one app.
I would'nt even complain about the instability of MC as it is my choice as to whether I take beta updates or not. My concern is that some of the stability has gone backwards, and what I mean by that, is that, for instance, the 'playing now' problem was rife, at least for me, a coupla months back. I did'nt 'complain' about it at the time and waited for a fix which eventually happened.
But now it's back and it's such a basic requirement within MC that it's almost impossible to run MC without it. I can't see that it could be caused by anything else than an internal MC error.
Also, the 'drag and drop' issue is such a basic requirement that, was working, and now is'nt. As I don't have this problem in any other app, I would consider this to be a problem within your app rather than anything else on my pc.
I use my pc mainly for music (MC only - no other 'jukebox' software), emails, banking and little else. There's very little redundant software and certainly no redundant hardware. The machine is housekept on a weekly basis so, as you can see, I have no necessity to 'strip' it down - if it ain't broken, don't mend it.
I hope you see these comments as, at least, constructive. I've been using MJ/MC for a long time (and intend using it for a lot longer!) and getting into it after working all night, is one of my highlights. It's just, at the mo, coming home from work and selecting a coupla tracks only to see the whole lot collapse is fairly disappointing.
That said, it's a nice sunny day here in England and, life ain't too bad is it !!!
Have a nice day Jim
Jim
