For what it's worth, my client who has been experiencing this problem is using OE 8.1A. At this point they are convinced that Adagio isn't robust enough for their needs and are in the process of evaluating other software. This is the exact issue that is making them doubt Adagio's robustness.
Network issues such as this are not my forte, and I don't want to spend time looking foolish grasping at straws trying to diagnose the issue. If someone at Softrak wants to contact them, I'd be happy to provide the contact info - they are very tech savvy.
