VFP 6.0 SP3
I have a report that I am running from a menu selection. The menu procedure is a follows:

Local lnSelected
lnSelected=Select()
Copy To CliReport.dbf
Use CliReport
Report Form Client To Print Preview
Use 
Delete file CliReport.dbf
Select(lnSelected)

When the report is complete and I'm returned to the main application, all of the tables in the data enviroment are closed. I tried a private data session in the report design. Same thing.
does anyone know what can be causing this?
TIA
