Eh, reinstalling your MS Word or your VC++ libraries would help. But unless it's an internal corruption of the libraries, then it might be malware or some virus. Try to do a scan to fix problems, then try updating your computer, and if nothing else works, reinstall Word.
Anyway, does this happen randomly, or does it happen only when you do something specific, like clicking a certain button or typing a certain letter?
Happiness is not about being perfect.
It is about seeing beyond the imperfections.
