I am currently without a system administrator. As you know, we are currently without at GEMPAK support person. ;-) We'll try to figure this out. I was able to run gdtopo on my machine, but changed the GAREA to 37.5;-108.0;45.7;-101.5 (I suspected you wanted 101.5 west). But even with 101.5 east it didn't die like yours did. What version of GEMPAK are you running? Was this a binary install or was it built from source? What operating system is this running on? Has the OS been updated since GEMPAK was installed? Thanks for the info. Don Murray Ticket Details =================== Ticket ID: XHX-768464 Department: Support GEMPAK Priority: Normal Status: Open
