I agree. It looks a puzzler.

But I can't reproduce that event sequence here by just using simple objects.

Do you have the above script in a single object (e.g. a button) or in a group?

Is the target for the events always the same? Check by adding "the 
target" to the trace lines. e.g.:

     put "mouseMove" && the target & cr after lvEvents
