Is Microsoft Word still unstable?

Back in the 90s and into the early 2000s it was REALLY unstable. I have a tendancy to push programs to their limit (as far as I know them) and Word would invariable lock up, freeze up, freak out, and create problems across my computer (which is why I stick with Excel if I can.)
It seem to have gotten a little better over the years, or maybe I just quit pushing it, but here lately I notice my FB hanging up sometimes. I check and I’ll have a Word document open. I close it out it it seems to release whatever. For example, I was waiting and waiting and WAITING for a picture to upload on FB. I killed the Word document that was open, and instantly that picture posted. Perhaps that was a coincidence.

Can our resident computer nerds share their thoughts with me?
