SYMPTOMS
If you create a simple dynamic data exchange (DDE) link from a summary task to a normal task, Microsoft Project may become stuck in an infinite calculation loop.

STATUS
Microsoft has confirmed this to be a problem in the Microsoft products that are listed at the beginning of this article.

Steps to Reproduce Behavior in version 3.x
NOTE: These steps may or may not produce the problem in version 4.x of Microsoft Project. The problem can still occur, however.


 * 1) Enter 3 new tasks.
 * 2) Select Task 3 and press ALT+SHIFT+RIGHT ARROW to demote the task and make Task 2 a summary task.
 * 3) From the Table menu, choose Summary.
 * 4) Move to Task 2 and select the Schedule Start, Scheduled Finish, and % Complete fields. From the Edit menu, choose Copy.
 * 5) Move to Task 1 and select the Scheduled Start field. From the Edit menu, choose Paste Link.
 * 6) In the % Complete field for Task 3, type 5%.
 * 7) Change the Duration field for Task 3 to 2d.

At this point, the screen appears to be flickering.

To temporarily stop the endless calculation loop, you can choose the Links command from the File menu and clear the Remote References check box. Disabling this option turns off the updating for the links. If you make a change and want to update the linked data, you can reselect the option in File Links and turn it back off after the link is updated.
