Problem

MS Word 2007

If you can't open a .doc file unless you open MSWord -> Open -> filename.doc

Also, your cursor/mouse can't click or right-click/select anything in the typing area, scroll bar on the right and margins but it can interact with all the other objects in the Ribbon bar, basically, everything but the part where you can type.But, you can use the keyboard Ctrl+A (and it allows you to select all the text).

You've also had trouble closing MSWord properly too. Every time you close, the message box "Microsoft Office has stopped working...." then "....is restarting"

Furthermore, when you go into the Options, the window opens with the list on the left "Popular, Proofing, Save, Advanced etc.). You cannot select anything here (can't use keyboard either) on the left bar pane so you can only access the Popular tab where you can change most popular options like Color scheme or User name. This only happens in MSWord but works perfectly fine in MSPowerpoint

You've tried the Repair option in Control Panel but that didn't do anything. You updated the 2007 Office Suite using Service Pack 1 as well and that did nothing.

Fix

Start, Accessories, Run

Enter "regedit" and hit enter

Now look into:

HKEY_CURRENT_USER\Software\Microsoft\Office\12.0\Word
Find the "Data" folder and rename it to "Old-Data"
Start Word again and the problem is fixed.
It seems its due to a change in the standard settings in the last office update - and hence has nothing to do with drivers or vista sp1 etc.
