Brendon,
no I hadn't tried any of the other schematic tricks that you mention. I
wouldn't be able to use the ports for connections, don't have any, don't
usually use them. Just nets globally.
Duplicate designators aren't an issue unless they have some manner of
getting past the ERC check
Brendon,
it is on Brad defined netnames! Does that mean something to you? I have
looked over the nets in question very thoroughly and cannot find anything
unique to them. I use similar netnames right across the schematic but only
these 14 are causing problems.
P.S. these netnames don't cause
Duplicate designators aren't an issue unless they have some manner of
getting past the ERC check for that situation.
Duplicate pin number errors are not always caught at the schematic
level ERC and can cause the alternating net connection on update.
Seems an unlikely cause since you have 14
you can also globally change all of the nets colors using the same method
listed below then hit global. it will change all of the colors

Brad,
This is somewhat related, I did see the exact same thing happen to
another designer here an dwas not involved enough to determine
what had happened, but just some nets had connectivity
problems and also it put parts off the design area on first

Brock,
thanks for the suggestions. The real problem is not the nets
toggling which is similar to duplicate pin numbers but in this case why is
it continually generating these duplicate nets? Once the duplicate nets are

what exactly do you mean by a clean copy of the schematic(s)? I
picture copying everything from one schematic page to another new page. But
what would this accomplish? I would be copying everything, or are you
looking to not copy items which 'may' be off sheet?
Sincerely,

Brad,
Sorry for the confusion.
I thought things off sheet (or really editable area) were footprints in the

when mentioned before?? I thought that was waht was mentioned??
What I meant by clean schematic
in my case was to start over with the original Orcad
schematic and import it into Protel
Hi Brad:
I misunderstood the problem as originally described, but
I have seen the duplicate net problem you describe.

generated then the nets vacillate back and forth between each duplicate with
each successive update. (i.e. disconnect pinX from net y, connect pinX
Brock,
what you describe sounds very similar to the tact that I took at
first, however I have not used busses on this design. The connections were
all individual wire connections, all with unique net names. I did however
search out and destroy any duplications of the netnames on any

One instance where this fails is on a symbol with multiple component names.
The schematic library keeps a list of component names assigned to a symbol.
The 'update' process apparently only looks at the first component name in
the list. If your schematic symbol has a different component name at

the one thing that is commonly a problem with this is that people

One other thing - (as I recall) only open schematic pages will be updated,

Is it a bug? Well, that all depends on who you ask. For the king's men

nothing more than a minor nuisance, nothing worthy of anything more than a

You could un-group the sch symbols by deleting them from the group in the library.
Each part will then have its own symbol and the update should work.

has been ) set to 10. It only happens sometimes. Does anyone know the

Black Oxide is used to enhance adhesion of prepreg to inner layer
cores. Since the process is used anyway, I imagine that any fab
shop could provide black oxide on outer layers too if it was
requested.
I guess some LPI compositions have had adhesion difficulties in
the past, leading fab shops to

Yeah, it seems to be pointing at a problem with the synchronizer when used
