We've got a little 4 computer peer-to-peer network. Primarily 2 computers use Sage 50. They are new. Core i5 4th generation 8GB of RAM, Solid State Drives running on a gigabit network.
One acts as the server and the other one access the data over the network. The server stores Sage 50 data as well as Excel Data.
The 2nd station often has excel 2013 files open as well as Sage 50. Excel 2013 will stop allowing the user to access any of the fields/cells. However, it does not lock up or say "not responding". And there is absolutely no errors that show up in windows event logs of either application or system event logs.
I have googled and re-googled, but have not found anything even remotely similar to this.
The station has never had anything but Sage 50 2014 on it. The Server may have 2013 and 2014 on it.
