Are your Library parts built with the pads on the top or the bottom? If you build a library part with pads on the bottom layer, when the component is placed on the PBC it will record itself as being on the top layer, even though all the pads are on the bottom.

I've been plagued with this on my last 2 double-sided boards, and it's making things like assembly instructions a nightmare... Components that, for all the world, look like they're correctly on the bottom of the board - pads on the bottom, silk-screen on the bottom, not mirrored, etc. However, the components claim to be on the top layer. Any attempt to put them on the bottom layer puts them on the top. This looks like knowlege base item 2034, except that a) I've only ever used Protel on this design (The KB item says that it occurs when you import files from Autotrax and Tango - I suspect it also occurs when a file is imported from Protel - it's somthing I've done on both of these projects) b) They say it's fixed in SP6, which I'm running. The workaround isn't an option, since I don't have PCB V2.x , so I guess I'm going to have to unplace all those components, and place them again. This is going to take many hours, so any hints for a better plan would be gratefully accepted. Until proven otherwise, I'd recommend people doing double-sided designs to stay away from the file -> import (and cut&paste) in the explorer window. It's particularly troublesome, since I didn't notice the failure until I'd shipped the gerbers...
