Yep, it does indeed re-run the report with each ZOOM. This means it also runs any DE method code associated with that report, and, if you're using NOWAIT, instantiates a new DataSession with each run. Very tricky, and not well integrated with the rest of the environment.

The only reason I can come up with for this is that zooming causes the report generator to repeat the process of building the preview image from the table input.
