Crash while switching Playlists

Hi,
I used Cross DJ for about one year now, till i updatet to Cross in december. Win 7 with Cross 3 and 2 cdj 350 in hid mode and the djm 750 as a soundcard. but since i updated to the full Cross, i had Problems switching to playlists, because as i am lazy as (don't write f...k thanks)), i put the shortcuts of the playlists to the left side (right underneth the collection iTunes autoplay and prepare list). But theres one Scenario that makes Cross Crash. I'm in a playlist and want to view another one by pushing the "back"-button on my cdj 350. then i use the select button to select the playlist i want. No Problems so far, BUT when i push the select button as i would do to load a track there is a short "beep" and the Screen gets a bit White (please have a look at the screenshot) this probably f**ks me up. I hope you know a solution for this, because i had it several times on b-day Partys and even on the Radio ^^
sorry for my bad englisch, i'm german, but in the german Forum i did't find a Support toppic
