Show Cue System

My cues in the cue list are disappearing one-by-one, in order. The weird part comes when the cue that was previously gone comes back. The editor is fine, all cues are set to display cue, and I see no reason why this is happening. I have a diag. dump file and below is basically what is happening.

Cue list: I, K, L, M
Then I do some action like scrolling.

etc.

Thanks

Strange. Could you email me the diagnostic dump file?
