Can't open and close Word doc

[onruyu]

I faced some problems while using Word doc.

Firstly, I wasn't able to open my Word doc by double clicking. Also, I
wasn't able to use my mouse cursor while editing my doc as well as doing a
right click. And most of all, I can't close my Word doc. When I try to, it
says 'Microsoft has stopped working' and then 'Microsoft is recovering your
doc' and Word restarts itself (creating a new doc this time).

Can someone please help me? Thanks.

That's a symptom of a Word Data Key corruption - usually because Word has
been running when updates are installed.

Run Regedit and expand by double-clicking to the key below. With DATA
selected, press DELETE. Word will automatically recreate a new key when it
is restarted.

HKEY_CURRENT_USER\Software\Microsoft\Office\12.0\Word\Data

Symptoms of Data Key corruption include:

• The mouse does not work when you use Word.
• You cannot open a Word document from the Search window in Windows
Vista.
• You cannot open a Word document from Windows Desktop Search.
• Word crashes when you try to start or exit Word.
• Word crashes when you open the Open dialog box.
• Word crashes when you save a document.
• Word crashes when you close a document.

If you feel uncomfortable editing the registry yourself, Microsoft have a
fix that will do this for you.
