Mira, it seems that you may have sorted out your difficulty with opening the schematics in question. I would have suggested the printer issue as Dennis suggested. The printer bug will crash Protel if the schematic was an open document while opening the database, otherwise it may crash the program when you try to open the schematic within the open database. Of particular note, I believe that it is always necessary to have a valid printer configuration set in order to view or open a schematic. For this purpose I have a phantom printer installed on my machines LPT1 port just in case the network printers go down or are otherwise not available through the network. As for your query about wires or lines. In Protel, unlike other systems, wires connecting symbols in a schematic have no net information carried within the wire if you query the wire properties. The net connectivity is directly assigned at a time when the netlist is generated, at that time it is not stored within the schematic but will be regenerated again if the netlist is generated or the PCB is updated via the synchronization facility. Until that time the net connectivity information is again transparent. If you use a net label to assign net names to a wire then the wire will utilize that net name when letlists or synchronization is generated. Using multiple net labels is a hit and miss situation where you would not be sure which net name is selected for use in the netlist, a single net name would be arbitrarily selected from the multiple names applied through the multiple net labels. Hope that helps explain some of the issues you raised over the last few days.
