The file size isn't the issue; I work on files a hundred times that size 
all the time.

Are you doing everything in a variable, or trying to display the 
contents in a field?

With that much data there's not much to see anyway.  If you can work 
with it in RAM you should find LC is more than up to the task.

If you're not using a field please post the stack and the data file if 
you can so we can poke around and figure out what needs to be done.
