Blimey. It worked.

I'm sorry I didn't mention it in my first post, but *.html files did
open with Opera even while R would crash. However, following your
suggestion, I looked at the Properties for an html file, and it said
"Opens with: unknown application". (Strangely enough, the file icon
was still Opera's "O".) So I re-selected Opera as the default
application, and everything went back to normal. Thank you so much for
your help!
