Important This article contains information about how to modify the registry. Make sure that you back up the registry before you modify it.

SYMPTOMS
When you open a master project in Microsoft Office Project 2003, and then you expand the subprojects, Project 2003 may stop responding.



CAUSE
When you expand a subproject in a master project, Project 2003 loads the subproject data on demand. Additionally, Project 2003 caches some extra data in memory for the subproject. Project 2003 cashes this data to improve performance. When the master project contains lots of subprojects, and the subprojects contain lots of data, the memory limit may be reached. When the memory limit is reached, Project 2003 stops responding.



RESOLUTION
Warning Serious problems might occur if you modify the registry incorrectly by using Registry Editor or by using another method. These problems might require that you reinstall the operating system. Microsoft cannot guarantee that these problems can be solved. Modify the registry at your own risk.

To resolve this problem, follow these steps:  Install Project 2003 Service Pack 3 (SP3).

For more information, click the following article number to view the article in the Microsoft Knowledge Base:

923622 Description of Project 2003 Service Pack 3

 Right-click MS Project, point to New, and then click DWORD Value. Type CloseSubProjHandleAfterOpen, and then press ENTER. Double-click CloseSubProjHandleAfterOpen.</li> In the Edit DWORD Value dialog box, type 1 under Value data.</li> Close Registry Editor.</li></ol>

STATUS
Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the &quot;Applies to&quot; section.

<div class="moreinformation_section">

MORE INFORMATION
After you install Project 2003 Service Pack 3 (SP3), and then you set the value of the CloseSubProjHandleAfterOpen registry entry to 1, Project 2003 loads the complete subproject when you expand a subproject. Project 2003 also releases the cached data. Therefore, Project 2003 consumes less memory. However, when you expand a subproject, the expand operation may take longer to finish. This is because Project 2003 loads the complete project instead of loading subproject data on demand.
