document.forms[n].<substitutedElementName>
or
document.forms[n][<substitutedElementName>]
return undefined.

Correct. I just tried it on a large document downloaded from somewhere 
and it seems to fail (returns undefined). I'll try to understand why. 
Anyway it doesn't crash. :-)

I filed a report to Opera's guys, but it remained unanswered. I had a 
page with 2 frames and a couple of frames in turn in every "main" frame. 
Trying to print a sub-frame resulted in an empty page. I think this is 
true for all version with Presto.

With Opera 9.<something> IIRC I was trying to implement a function to 
load a html page in a DIV. I made the thing creating an hidden IFRAME 
and then copying the elements from the IFRAME to the DIV, but due to the 
inconsistent state of the onreadystatechange (IIRC) I wasn't able to 
detect when the IFRAME was completely loaded, so I had to resort to a 
workaround, injecting a script at the end of the IFRAME... there has 
been a thread here time ago about script injection.

In IE the test when a IFRAME is put in designmode queryCommandSupported 
or queryCommandEnabled (I don't remember the details) is wrongly 
implemented.

Happily many problems have been solved, and now they are only ghosts of 
the past. Nevertheless when I started to tinker with ECMAscript 
implementations in browsers, the landscape was scaring. It is also 
possible I had access to incomplete/imprecise informations.

The point being, it was complicated for a medium-weight programmer, very 
hard for a novice.

Anyway, of course you know better than me the incompatibilities, 
moreover I did not trace all the cats I had to skin, so my list is 
widely incomplete.

Not so easy, mr. Spock! :-)
Forms are generated server side by a general purpose function, and I 
implemented only form controls, so it would be messy to try to modify 
the function, while the Input element is supported, so I use an input 
(readonly) and I can live with it, as long as I can do a replaceChild(). 
In perspective, after discovering the IE bug and after having devised 
and written nodeFind() to circumvent it, I must admit that it would have 
been less work - but c'est la vie!..
