INFO ONLY for those suddenly having "no response" with MS Office 2003/2007 Word:

Weeks ago I suddenly got a problem with Microsoft Word (Office 2003) usually failing to respond , unable to open or save files, and just "hourglass thinking". In fact I frequently had to go to Task Manager to close it. Tried everything I could think of and read in sites (renaming "normal.dot", reloading MS Office 2003, loading MS Office 2007 with same result, removing Adobe 9 Pro that had been loaded a week before, using "repair" command.............and nothing worked. Finally I found a solitary blog input somewhere saying that the person with same problem on Vista resolved it by uninstalling "Office Live DD-on 1.4". I had installed that a few weeks before I discovered the problem and never used Office on Vista PC since installation. I uninstalled "Office Live Add-ON 1.4" after many hours of trying other things.............and PROBLEM FIXED!
On my XP laptop and desktop, that Add-On has no impact on Office programs but is apparently a problem with Vista. I did not see any such notice on Microsoft site.
