Here is what I have noticed:
click on "settings" - "options" causes it to freeze while trying to open Options dialog box.
right click on a song to open "properties" and the "properties" box opens but the bottom portion is kind of funky; it shows what was behind it almost like a dialog box that freezes upon opening but you can still navigate the tabs under properties.
Click on "playlist" then "recently played" and select a song, any song, and it starts playing and crashes.
click "playlist" then right click "add new group" adds a new playlist group and crashes it.
Something is different about the library backup. Before I uninstalled 7.2.280 I "backed up" my library, and it creates those .jmd files. But now when I go to "restore" in the new MJ, it asks me for a .zip file! It can't open .jmd files?
So, I used winzip to put the 5 .jmd files into a .zip archive which MJ opens. All my song & tag info is there, but the links to external cover art files are gone from "properties" view.
Click on one of my playlists, it crashes.
Is this a known bug, all these crashes? Is anyone else getting lots of crashes? What am I doing wrong?
