What's the OS? How big are the images (shouldn't make a lot of difference, but big images do make for bigger previews)? Machine specs?

You didn't say which version of OS X... Did you migrate ID to this machine, or do an in-place upgrade on the OS?
You should have a crash report. Please post it on Pastebin.com (NOT HERE) nad put a link to it here.
Using a Casper Server as the distribution point, we initially upgraded the machines from Snow Leopard/CS5 to Lion/CS5. Then we upgraded from CS5 to CS5.5 on Lion. Then we migrated from Lion/CS5.5 to Mountain Lion CS5.5 10.8.3.
We are now on CS5.5/ ML 10.8.4
InDesign does not do well with migrations or in-place upgrades. You should uninstall, run the cleaner tool (CS Cleaner Tool for installation problems | CCM, CS6, CS5.5, CS5, CS4, CS3) and reinstall clean.
Peter, thanks a bunch for due diligence on this. we will give it a shot. I did have the activity monitor up when my Designer was making changes and updating via Dynamic Link on these files, and the processor was showing 100-103 % use (5-6 GB RAM). Could it just be limitations of our hardware?
I'm sure it's at least partly that. An i5 is bare minimum good enough to run ID, in my opinion. As for the RAM, ID CS5.5 is only a 32 bit program so it never is able to use more than a bit under 4 gb, so hard drive space and speed also become factors with large files.
