Word "save as" lock up

Clarifications

This worked for me.
1. Open up Regedit. (Go to Start and type "regedit" in the search field and press enter.)

2. In Regedit navigate to HKEY_CURRENT_USER\Software\Microsoft\Office\12.0\Word\Data
3. Right mouse click on the "Data" folder and delete it.

4. Open up Word, close it, and voila, problem solved.

If you suspect the printer it wouldn't hurt to uninstall, and then reinstall it to see if it resolves it.

I have seen this type of behavior if you have an external HD,Flash card reader, or some other type attached device that Explorer has to open when you do a "save as".

You can also open Word from the run line with a switch type in winword /a to reset it.

Step 1. Check Word's Startup folder.
NORMALLY, IT SHOULD BE *HERE*

C:\Documents and Settings\YOUR USER NAME\Application Data\Microsoft\Word\Startup

HOWEVER, SOMETIMES IT ENDS UP IN YOUR OFFICE INSTALLATION - AS IN:

C:\Program Files\Microsoft Office\OFFICE11\STARTUP

CORRECT IT BACK TO YOUR DOCUMENTS AND SETTIGNS LOCATION - AS IN (AGAIN):

C:\Documents and Settings\YOUR USER NAME\Application Data\Microsoft\Word\Startup

printers and mapped network drives that are installed but no longer there/available. Will cause this issue. I would double check and make sure all your devices are "really" there...
