Yup, that’s the latest official release.
I’ve tried accessing music via a media server (TVersity), then going back and starting a photo slideshow whilst the music continues playing. Left it running for about 10 minutes and no reboot.
Currently doing the same via network share but no reboots yet.
Are you accessing your music / photos via media server or network share?
Also, are you viewing Flickr or photos stored on the server? If on the server, how big is the slideshow and are any photos unusually large in dimensions or filesize?
Are you playing regular MP3s or some other format for the music?
Hopefully someone else running the 1.01.24 firmware can test this out as I’m running a beta firmware.
On the other hand, if I’m not having an issue with it, chances are the next official release will work better for you. :)
