[sylpheed:35602] Using External Editor - Problem

[Harry Benson]

Hi, new user to Sylpheed (3.4.0.2 Beta) but I love it so far. Being
rampantly Dyslexic a spell checker is not a luxury but a necessity.

I searched and read and tried installing GNU ASpell ( the ISpell
replacement) as per instructions, then added the recommended text into
the "External Editor" field, but clicking the "Editor" button did
nothing when writing a reply.

OK, next option I found SynWrite (SourceForge) which has an inbuilt
spell check. I used the full path and program name for the "External
Editor," and checked the "Launch external editor" option but when I
select "Reply." I get the standard internal editor.

So, what am I doing wrong?
How do I fix that?

I REALLY would love a spell checker within Sylpheed and I hope that
the developer takes pity on the Dyslexics of the world and adds in
Hunspell or something in a coming version.

Thanks
