Layers problem

I typically record multiple takes on different tracks and comp across tracks.  After reading aa post by Anderton, I decided to try using layers again.  When I record a subsequent layer starting mid-song, all other tracks (background vocals, etc) are way behind the current layer as I'm recording.  However, the clip is in the correct location in the track after recording.  I have tried saving, rebuilding layers, resetting Now Time, to no avail.  The only thing that works is to save & close X1, then when I re-open it works fine for the first new layer I record, then back to the same thing.  So I have to close and re-open between each layer.  Obviously I have something set wrong.  Any suggestions?

I'm using WDM drivers, buffer size set at 14 msec / 616 samples.

It's purely an audible problem.  it seems the track I'm recording layers on starts at the Now Time marker, but all other tracks are starting at the beginning of the project and playing from that point.  All layers appear to be laid down at the correct point in the project after recording -- it's just unnerving listening to 2 different points in the project at once and trying to record!

Only have a few basic effects turned on right now -- built-in Cakewalk Fx.

Thanks-

Late response -- been outa commission for a bit...

It's a Cakewalk interface (UA25EX).  Never had it happen before but also had not used layers before.  Now that you mention it, I recently changed back to WDM driver for a particular project, perhaps it's related to that...?
