SYMPTOMS

Assume a situation where you are working with a Microsoft Office XP document that contains an ActiveX control. The Active X control updates the data that is in the control.

In this situation, the Private Bytes counter in Performance Monitor may continually increase. Additionally, if you close the Office XP document, the resources are not released.

CAUSE

This problem may occur because the Mso.dll file creates EMF files when the data is updated in the ActiveX control. Therefore, the path of each EMF file that displays the ActiveX control changes. These changes cause an increase in resource usage.

RESOLUTION

How to obtain the hotfix

This issue is fixed in the Office XP post-Service Pack 3 Hotfix Package that is dated September 6, 2005. For more information, click the following article number to view the article in the Microsoft Knowledge Base:
