>The report is called using Report Form from within a method of the form with the private data session. It doesn't use report variables but does use 2 public variables as explained in my reply to David. I'll try the Noconsole command and thanks for your input. I'm really out of ideas here.

Can you make these two variables private? They still would be visible in the report.

What is the name of this array? Could it be named in such a way that it somehow interferes with VFP internal code?

Also do you have CLEAR ALL or RELEASE ALL somewhere?
