[protel dxp] pcb import design from one of schematics in a p

[xiangyu.yang@gmail.com]

Hi all,
My protel DXP project has multiple schematics. Now I want to draw a pcb
for one of them. But when I _update PCB_ (in sch menu) or _import
changes_ (in pcb menu), I can't specify the destination and the 1st
file is always chosen. Please help me!
