Microsoft Excel Hangs When Creating a DDE Link to KEPServerEX V4 or V5

Last Update: 11/7/2018

1. A Microsoft Excel spreadsheet that contains DDE links hangs when it is loaded.
2. A new Microsoft Excel spreadsheet hangs when a DDE link is added.

Possible Cause:
When open, the Google Chrome browser blocks DDE connections to Office products. This is a known issue and does not impact connections from the server to Excel.

Close Google Chrome before making a connection. Once made, Chrome can be re-opened and additional connections can be established.
