VFP 8, SP1, Windows XP

I can't search now, but I seem to recall there is a problem (and a work around) with the following syntax when the focus is on a grid:

select (pcTable)
report form (lcReport) to printer prompt preview

The form has a pageframe with 10 pages. On each page there is a grid, 9 of them have a local view as a record source, one has a cursor (cursor is created in Load using create cursor...). The cursor is populated by users exporting selected records from the 9 views.

To print, users select any numbers of records in the grid, then right click to get a shortcut menu, and select the print option. Selecting records and shortcut menu are part of a gridselect class, essentially a shape covering the grid.
The above code to run the report is actually a procedure in the Cleanup of the shortcut menu.

The sequence is this:
1. the preview is displayed - which means we are on the corect area at this point
2. click on the printer in the print preview toolbar
3. the print prompt is displayed
4. click on OK to print
5. we get the error 'Variable XXX is not found' (where XXX is actually a field name in the cursor that is used in the report)

We log the error and environment at the time of error, and we can see that the pcTable contains the correct alias name, but the currently selected table is NOT the pcTable. It is significant that the selected area is correct at the time of preview, but it is changed between preview and print.

We only get the error on the page having the cursor as grid record source.
We do NOT get the error when:
- preview/print from the 9 pages on local views
or
- step through the code in Debug

There is no timer, and no filter on any table.
The report calls one UDF which only formats the date to a specific format, it does not change work areas.

TIA
