There's certainly something up with 0.0.4 on PR1.2. Sometimes the player simply crashes and then hangs up in the background. Sometimes during playing a video the pop-up menu hangs and is stuck only half-hidden. In such case after closing the player it also remains stuck in the background.

Finally, sometimes playback is okay and OVP seems to work okay, but after closing it keeps running or at least hanging in the background blocking e.g. USB access to MyDocs.

Note that any "sometimes" can mean here a few days or few hours. I was using the player for a few days without any issue and then it hanged up on me 3 times in a row on another day, so its random.
