Hi there!
I'm having this problem with MC crashing when it fails to download the images for the Theatre View background.
I have MC running in my htpc in theatre view mode, and set to show the artists photos in the background.
Since some old build, if the internet connection is for any reason unavailable, when I'm browsing the albums of an artist or when I'm listening to some song, MC menu navigation becomes unresponsive and after a while MC crashes.
This happens only when it is in Theatre View mode. If it is in standard view then no problems, but when I switch to theatre view, after a while, again, it crashes.
If the connection is on, the images are downloaded correctly and MC never crashes.
I've tried some old builds and found that 15.073 gives no problem.
I'm using MC 15.142 at the moment, running on Win XP SP3 (fresh install made some days ago).
I've sent you a few logs by email to logs at jriver dot com.
