Hi Simon,
You're welcome and thanks for the feedback.
To your question of "turning off contouring", Project automatically uses
a "Flat contour" by default. With a flat contour the work for each
resource is spread evenly based upon the assignment units and the start
date/time of the task.
The only way that I know of to change the contour to something other
than flat is to either double click on the assignment (in the Resource
or Task Usage view) and select a contour other than flat or manually
edit the work per day on the assignment. The manual edit could also be
happening due to recording actual work.
Again, a contoured work on a task is not a "bad" thing -- particularly
when it happens because of actual work.
I hope this helps. Let us know how you get along.
