Hello, my name is XXXXX XXXXX I will try to assist you with this issue.
Which version of Office are you using? Also, what internet security software are you using?
Are you having trouble with Internet Explorer as well?
Sometimes, an internet security program can cause the issue you are seeing. Usually, to test this type of issue, you can do the following:
1. Click Start>Run.
2. Type winword /safe , press enter (Word will open in its 'safemode version')
3. Type a test document, then save and close.
Does Word close properly?
Also, just to be sure, open your internet security program and run the updates for it. Once completed, try using word again (not using /safe) and see how it works.
