There is no spellcheck in mozilla !

I added it in ver 1.2 and it is still working in mine!  All except for this one
page which causes Mozilla to crash.  :)

You´ve got to read the Release Notes for 1.3.1, if you upgrade from 1.2 to 1.4b ;-)

From the 
New Additions to the Release Notes 1.3.1
...
The mozdev spellchecker released for earlier versions of Mozilla does not work
with 1.3.1 or newer builds and will lead to crashes. Please upgrade to the new
spellchecker ( bug 185251 )
...

Yep. You were right.  Downloading the new spellchecker for ver 1.4b fixed it.  

Seems like if Mozilla is going to be unhappy with an earlier version module
there would be a flag in Mozilla indicating what minimum version was required
for all of the accessory modules such as spellchecker.  I guess this will
eventually sort itself out when spellchecker becomes an integral part of Mozilla.

The more general issue here is that mozilla doesn't appear to check the
compatibility/versioning of plugins, or attempt to handle errors they generate.
A misbehaving plugin can bring down mozilla.

I've done some digging on spell checking related bugs and found a number of them
that all boil down to this issue.

If this hasn't been done already, you (the Mozilla bug team) should consider
creating a new bug report for this issue.

This is no simple plugin and we can't do anything to avoid such crashes.

-> no patch in mozilla = not fixed

Can't check (for instance) a spell checker plugin for compatible version number
so as to be able to avoid using an older and not compatible version???  

SURELY you JEST!  Software has been doing this for 30 years that I KNOW of!
