VB.NET app - Parameters passed don't always work

VB.NET app - Parameters passed don't always work

VB.NET app - Parameters passed don't always work

I have a strange problem, I'm hoping someone has run across before.  

I'm using VB.NET(2005), Crystal XI R2, SQL 2000

I created a windows app that uses the reportviewer.  I have a front end form to select the data that is passed to the crystal report's parameters.  After the first report is loaded I can, within the reportviewer form, cycle through customers, which loads a new report for the selected customer.  This will work fine for say 3 customers (it's not always 3, just a random number of attempts), then all of a sudden, when I move to the next customer, I get prompted to input parameters manually.  If I close the parameters window and reload the same customer, the report loads fine.  This happens randomly and I'm not sure what's causing it or how to get around it.

If I could find a way to test if the parameters were NOT loaded properly, then I could just retry and it would likely work on the second attempt.  However, I cannot figure out a way to test that the parameters were passed correctly.  Can anyone point me in the right direction with this or possibly explain why it's behaving this way?  Thanks
