Word 2007 user gets messages that she has exceeded the maximum allowed characters in an open document
I have a user who has a Windows 7 32-bit operating system laptop. The laptop has 4 GB of RAM (of which 2.92 GB can be used). The Swap file is set to be managed automatically by the operating system.
She is running Microsoft Office 2007 Enterprise. Her Windows 7 and Office 2007 software are all kept up to date by installing the latest Windows updates.
Sometimes while several Word documents are open at the same time (like 8 or more Word documents which are all saved--only minor changes and edits have been made to each document) she gets error messages telling her that the document has exceeded the maximum number of allowed characters. This happens within Word documents that have only around 10 pages and around 5,000 characters. The user is also running Microsoft Outlook at the times that she gets these error messages.
While these sorts of problems can be fixed by reducing the number of open Word documents (or by closing all open documents and then rebooting) we would like to find a more permanent solution to fix this issue.
One possible solution would be to replace the user's laptop with a more powerful 64-bit laptop that is running Windows 7 64-bit and that has more RAM (like 6 GB or 8 GB).
However, we are hoping to fix this issue without having to replace the user's current laptop or operating system.
What are some possible solutions or adjustments that can be made to fix this issue so that the user won't get these sorts of error messages?
