Resolve is cross fading audio without being asked to

Hi,
This is only happening with one cut in my timeline.
THERE IS NO CROSS FADE applied to this cut.
When the two clips are up against each other, I hear the audio from the first clip continuing over the audio of the second clip for about a second.
If I pull the two clips apart, the audio played when playing the second clip is solely the audio of the second clip.
If I put them back together, the problem comes back.
Also, if the clips are not side by side in the timeline, and I play through the first clip, the audio starts to fade to nothing at the end of the first clip. I see no visual cue of anything being applied to the end of the clip at all.
Has this happened to anyone else? I would greatly appreciate some help - as usual, these things catch one up against a deadline...
Thanks!
