Hey, I'm having a similar problem. Just started a while ago (maybe after some Windows update cuz my friend had a similar problem). It was working fine a week ago.
Anyway, most of my MSOffice programs run perfectly fine except for MSWord. I can't open a .doc file unless I open MSWord -> Open -> filename.doc
Also, my 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, I can use the keyboard Ctrl+A (and it allows me to select all the text).
I've also had trouble closing MSWord properly too. Every time I close, the message box "Microsoft Office has stopped working...." then "....is restarting"
Furthermore, when I go into the Options, the window opens with the list on the left "Popular, Proofing, Save, Advanced etc.). I cannot select anything here (can't use keyboard either) on the left bar pane so I can only access the Popular tab where i can change most popular options like Color scheme or User name. This only happens in MSWord but works perfectly fine in MSPowerpoint
I've tried the Repair option in Control Panel but that didn't do anything. I updated the 2007 Office Suit Service Pack 1 as well and that did nothing.
Any suggestions? I'm not too hardcore with techie computer stuff but help would be nice ^^
