I am running ArtPro 8.6 rev2, on OS X 10.4.11. The error I receive is: "Severe error: UnmappedMemoryException (4)) There is nothing in the file aside from black text, all converted to outlines. Importing the file on another ArtPro station yields no problems. All of our Macs are configured exactly the same (all running 10.4.11, 4 gigs of RAM, 2x2.66 Dual-Core Xeon CPU) I get this error sporadically, and it doesn't happen on every file. I've seen the error message upon importing, printing and/or using the Tabular Step & Repeat module. Does anyone else get this error while using ArtPro? I never see it while using any other application. I would think if I had bad RAM, my Mac would be crashing while doing other things. Any idea?
