Jeff...

Just wanted to let you know that I solved the losing-the-datasession-in-a-PREVIEW-NOWAIT problem. :)

In the OpenTables of the report's DE, I was executing code in a method belonging to an object that was instantiated in a *different* DataSession. I've now learned the hard way that you can't reliably call object code from one datasession if that object was created in a different datasession.

In the end, I just put all the code explicitly in my OpenTables (no more method calls to manipulate data), and it works fine.

Strange new issue, tho: I now can't make the preview go away. Any idea how to close it down programmatically?
