SYMPTOMS
When you try to open a large Microsoft Word document or Word Mobile document from a secure digital (SD) memory card on a Microsoft Windows Mobile 5.0 software for Pocket PCs-based device, you may experience one of the following symptoms:
 * The document may not open.
 * The document may take a long time to open. For example, the document may take two to three minutes to open.

Additionally, you may receive the following error message:

Unhandled exception in COREDLL.DLL (0x80000002: Datatype Misalignment)



CAUSE
This problem occurs because of an architectural limitation in Word Mobile. Word Mobile is included with Windows Mobile 5.0 software for Pocket PCs. Typically, this problem occurs when a document contains complex content. For example, this problem may occur when one of the following conditions is true:
 * A document contains many tables.
 * A document contains one table that has many rows and columns.
 * A document contains many list elements.
 * A document contains many paragraph changes or format changes.

A document that contains complex content uses lots of random access memory (RAM). This may cause the Windows Mobile-based device to run out of memory.



MORE INFORMATION
Typically, the document opens as expected on a Windows Mobile-based device by using Word Mobile. In certain situations, other applications that are running on the Windows Mobile-based device when Word Mobile is trying to open the document may close in order to free enough program memory to open the document. You may receive the Out-Of-Memory dialog box that has the following message:

The available program memory is critically low. Please close one of the following applications.

If Word Mobile cannot open the document, you receive the following message:

A problem with the document was encountered it cannot be opened.
