Hi, I installed my word 2000 many years ago, when I upgraded to win8 it worked OK but with w8.1 is still working except when I finish writing & go to save or close it a small windows appears saying ms word is not working properly as per attached scan. Then allows me to close down word. Anybody else suffered this? & can help? Also I just noticed that on the top menu next to Help this "PDF Pro 10" appeared.
