I double checked and yes, she is using the same dataset. She is also running the current version and all her other modules are current as well. I ran check sys and it showed no warnings or errors.

If I make a change on my AR, for example, if I post a cash batch, she can't see the transaction on the customer on her AR. When she made a change to a customer name from her AR, it refreshes on everyone else except for her! It's so strange.
