OK.

You probably record the "wrong" events. Erh, how did that sound?

Since X11 is asynchronous (no way to make sure that events gets send in 
the right order when replaying as when recording) we can rather easy get 
into a situation where we get a bunch of X events in advance and miss a 
couple of Y events (they will come later) when replaying. Xnee manages 
this by thresholds, but my experience is that setting them too high will 
lead to "more or less unsynced" behavior of your app. So I would go for 
investigating what events gets sent when you test.

But let's get down to your problem.

I tested oocalc a bit and noticed two things:

1) Xnee seems to be doing sth wrong when reading settings from command 
line and from recorded file :(

   Q&D solution: remove the three lines in your recorded session file 
that sets the thresholds


2) Try synching with event 15 (VisibilityNotify)

   Record:
   -------

   ./cnee/src/cnee --record --mouse --keyboard \
        --delivered-event-range 15 -o hesa.xns -sk p

    Note: recording stops when you press the key p


    Replay
    -------

    replay with thresholds set high (and one TOO high):

    ./cnee/src/cnee --replay -f hesa.xns --verbose -bv \
         -mat 100 -mit -100 -tot 400

     Note: -bv comes from a Xnee built with buffer verbose supprt.
           use it at will, but you need to enable
           "buffer verbose" during configure


NOTE: I am looking deep into the sync code at the moment!!!!
