Version 8.1b(090508)

We are having problems printing two reports within the Invoices module:
1) Open Batch - Listing
2) Deleted Invoices Audit List

For some reason they won't print or preview at all. We are able to print invoices and other reports without a problem.

Any ideas why this is happening. As a last resort, we can re-install Invoices.

Thanks
Karin
