Tony,
If you're around take a look at this and see what the problem might be...
This file is in X4 format and I can engrave it with no problem using X4. When I load it into X5 the only thing that engraves is the text. I checked the linewidths and they are the same (.72 pt) in both X4 and X5.
I've noticed some other problems with X4 files opened in X5. One I remember...everything in the file came in with an outline, where in the original X4 file they did not exist (such as the text all ended up with an outline around each letter). Also, in the same file, what was Black in color in the X4 file came in as a dark gray....
Here is the X4 file that won't work in X5.
Be interesting to see if you can find out what the problem might be. I have a feeling it may have something to do with the new color management in X5...but dunno...
