export to audio is messing up

I'm working on a project, it's 18 tracks, 24/44.1.  Several vocals, a piano track, and a few percussion.  Quite a few effects, about 4 sends, 3 subgroups and prochannel all over the place.  Softsynths are all archives, everything is bounced to audio.
 
It plays back ok in Sonar, but when I go to Export to Audio...as 16-bit or as 24-bit, I get about a 1/2 second pre-delay on the kick drum track, but only after the 3-minute mark, on the last chorus.
 
This is the only project in which this is happening.
 
I'm running X1 Producer on a DuoCore 6420 with 4GB RAM, Windows XP Pro, SSD + SATA drives, and my interface is an EMU 1820 on ASIO drivers.
 
Any thoughts on why this would happen?  Do the buffer settings affect this?

    Bump...update

    I've just upgraded my PC, and although the problem I stated above works ok now, it takes a really long time to render (which was happening on my old PC as well).  My new PC is Intel i5-2500 on Asus Z68 mobo, 8GB RAM, Windows 7 Home Premium, Sonar X1 Producer, EMU 1820 interface on ASIO drivers.

    When I export to audio, the progress bar goes through 3 or 4 cycles of "Processing Audio Data" which takes about 10 minutes in total, and then finally says "Exporting Audio" like normal and takes another 5 minutes to render the wave file.  This is for a 4-minute song.  This happens with a few of my projects that have more tracks and effects, etc. 

    Does anyone else have this problem?  Granted, it's faster on my new machine than it was on the old one, but still...over 10 minutes to render a 4-minute song seems not right.

    I've messaged Cake tech support about this, but haven't heard back from them either.

    Any help would be appreciated.  Maybe it's a specific plug-in causing the problem?

    "Processing audio data" is typical of audiosnap offline processing; maybe other offline processing too, but I don't know of any. Is that a clue?

    Thanks for the reply, bvideo.  I didn't use Audiosnap per se; I re-aligned the ruler using the "Set Measure/Beat to Now Time" feature, and then manually moved around some transients to line things up.

    Other than that, there's no V-Vocal being used, and the only effects are ProChannel and Sonitus Reverb.  There's also some volume envelopes.

    When you move transient markers, is it a good idea to "bounce to clip" when you're done?

    If you moved transients (not just the markers), you invoked audiosnap's rendering. Dragging the transient lines moves the transients, requiring rendering. Moving just the transient markers by grabbing the diamond does not modify the audio. Bouncing is optional. If you are completely done moving transients, and want to render it just once, or if you want to listen to the final product quality as you continue to work on the piece, you can bounce it. It will take a while "processing audio data" as the first phase of bouncing. It uses only one cpu.

    Thanks bvideo!  That's just what I needed to know.  I'll try it that way later on tonight.

    Update: tried bouncing each clip one at a time, and now export to audio works smoothly.

    Only this is, I thought there would be some indicator as to which clips had transients edited, like a different colour on the transient marker, or something?  I couldn't tell which clips I had edited and which I had not.
