I have a client with QRW 6.2a and we have run into problems with it.
AR/OE 6.1b

A report modeled after OE 6.1b invoices and credit notes has these following problems.
1. Attempts to create record filters do not seem to work if you have more than two selection criteria. Provides 2 and generates the report.
2. Attempts to export to excel 5 crash with a message "Report has more than 16350 records"

What is the problem here? Bugs in QR 6.2a? What can we do short of scrapping QR for win?
