Re: gEDA-user: gerbv potential problem
Unfortunately there's nothing in the gerbers to indicate where they came from. The schematic (a pdf) has a reference to Protel in it, which may or may not be a clue.

Re: gEDA-user: gerbv potential problem
Hi again! BTW I forgot to ask, is it possible to determine which CAD program that has been used to generate these gerber files? It usually says in the top of the file after some G04 remark command.

Wow, that was quick! Hate to think what that kind of service would cost commercially. Many thanks!

While I have been sleeping Julian has fixed the problem in CVS. If you're daring you can try out the CVS version. I've tested it and it looked like in your PNG's. It seems like it was one of the grey corners of Gerber that reared it's ugly head. This is the reason we like to release the code for public scrutiny to put some light on these dark corners. For those interested in the exact cause of this, please look at Julians explanation attached to the (now closed) bug report on gerbv's SF site. Thanks for your report and very good sample files.
