The Kilofox book refers to the report losing its datasession when the NOWAIT clause is used. I'm not exactly sure what that means, but I still think it is part of the problem.

>I do know this...you can create a report with a private datasession, and create a cursor containing what you need in BEFOREOPENTABLES. Then when you run the report with PREVIEW and NOWAIT, you can print from the preview button, and it does not crash. This is why I suspect it may be related to the datasession.

I have some hundres of ready reports. The temporary table for those reports
are prepared in a code from with private data session.
I want need to open a calculator over report preview window.
I cannot re-write all of those 100 reports by adding code to beforeopentables.

Genrepox is report extender. I like some of its features: create multiple detail bands in one report, get last page number using _grx_lastpage, writing
drivers. I think it is avaliable at eps software web site. I re-write it a bit to fix some bugs and adding some features. Unfortunately, Markus
seems not to support it more. Last version does not have documentation and
driver samples. I use older 2.1 version .hlp file and its sample drivers.
