If you type "opera:config" (no quotes, of course) as the address, there's a list of options. One of them is "fold linklists" (or it's in my version, anyway). Setting ite to off fixed a couple weird - and apparently unrelated - issues, including page anchors.
The fold linklists option collapses a list of links into a single link with a + next to it to expand the list.
