Thanks for your reply.
I am using HP LaserJet 4MP, they are using LaserJet III. The darnest thing about it is that reports with small amounts of data run fine, but reports with more than a couple of pages hang the entire system. I'm running a replication of that data over here on the same program just fine... In desperation I blanked out the tag and tag2 -fields in the beginning of the *.FRX -files to avoid any reference to printers as the report is run for the first time.
But to no avail.
