A client has a few workstations (but not all) that freeze when doing this: PO Receipt of Goods batch, then updating, the program would freeze with a message screen of "MAS is not responding" with choices to close the program or wait for it to respond Waiting, it would never respond. However, other MAS90 screens would continue to work properly. This has only been recurring in the last few weeks. All workstations are on Windows 10 Pro.

Any suggestions?

Note: Client has resisted to upgrading. They're on MAS90

This KB didn't help. Client does not have Teams installed, and testing only using the primary monitor gave the same results.
