One thing here. If codebase-wise these are identical, then those build
numbers (3500 for Windows and 6438 for Linux) are not ...

I typed in the address bar

javascript:alert("document.compatMode = " + document.compatMode)

and I was in quirks mode!

I never wanted to override rendering mode, furthermore never ever in
quirks mode.

It was set to 1 (btw, those values are absolutely meaningless,
unintuitive, non-informative by themselves and clicking the circled "?"
gives "No information on this item can be found"!); after clicking
[Default] button, the "CompatMode Override" value changed to 0 but I saw
no change when loading section9.5.1-vertical-positioning-float.html
testcase. I think I need to close and restart application.

I just restarted and it is back to 1!

Argh! I needed to scroll all the way down the long list of settings and
click the "Save settings" button! Geezzz...

Now, the 3 aforementioned testcases [1] are rendered correctly in Opera
10.62 (build 3500) under Windows XP

Ok. <...deep breath...>  To make a story short, the problem was with that
CompatModeOverride setting and not with Opera 10.62. So my fault here. I
will notify your colleagues Geoffrey Sneddon and Řyvind Stenhaug of this
good news.

Thank you for your time! I really appreciate this

best regards, Gérard
