Using a conventional keyboard, I can edit in the entry area of Wikipedia titles that I author i.e. type and text appears on the screen correctly.
However, when I come to type in the "Edit Summary" field of the Wikipedia entry, no text appears.

This happens only when using the Opera browser, and others all work as expected.
It's more annoying than serious, but I would like to be able to use Opera for Wikipedia edits.
