Lost lyrics

After entering lyrics into my music, i several times lost them.
I am using Cubase 6 ( now Cubase 6.01).
Does any body encountered the same problem ?

I thought the same thing happened to me with C5. Turns out I wasn’t paying enough attention to which tracks I was using. Everything was there, just in a different track. Haven’t checked C6 lyrics yet, but if you can give some details as to when it’s happening, I’ll check it on my rig later this week.
