Okay... After dealing with this silliness for several months, I believe I finally have it figured out.
I seldom print anything. My wife, on the other hand, prints reams of stuff. We have an HP952C printer. Since she uses it most of the time, it seemed to make sense to connect it to her computer (Dell GX110, Win98 SE), and share it over our network.
Opened Word 97, a while ago, to "fiddle". It didn't fail! What was the difference? Her computer was on!
To make sure, I closed Word, and shut down her computer.
When I reopened Word, I saw my old friend the application error.
The quick and dirty fix was to install drivers for another printer on my local port, even though there was no printer connected, and set it as the default. I'll research the "shared" thing as I get time, and pass along anything useful that I find, if anybody cares.
Strange.
FWIW, I was getting these same errors before I installed the Office 97 SR patches.
Thanks for your responses, tho'.
