NXS2 fw1.60 left with blank screen for 30 seconds

So last night I used 1.60, I searched for a track via the keyboard, loaded the track and then pressed shortcut button and playlist, went into a dance playlist and the screen was completely blank, no matter what playlist I tried to get into it was blank, I could go to track view and all my tracks on the drive were listed but playlists showed nothing, finally before I was forced to reboot the deck I went to the playlist vies via the back button and using the scroll knob and all of a sudden the tracks in the playlist appears

Havent had this happen in 1.5 at all and I use these same steps a lot, definitely a new issue

I will try and reproduce and capture on video if I can in the next few days
