Does anyone know of a Thai - English - Thai dictionary that can be downloaded from the net?  Ideally one that can translate both ways and as far as the Thai words, in both texts.

Don't know of a downloadable dictionary Trev, but can heartily recommend the Domnern Sathienpong Thai-English dictionary CDROM (Amarin publishing).  Search in English and Thai script with excellent quality speech samples.  

I picked up a copy for 300฿ here in Thailand.

That suggestion sounds good... where in Bangkok can I get a copy?

Good question Trev - I had trouble finding one in Bangkok and got mine from Surawong Book Centre in ChianMai.

You could try contacting Amarin:

NB:  If your using XP make sure you get the supported verision, else you'll need to get a patch.

I use an online Thai-English translator.

It's a lot faster than flicking through a dictionary.

Click on the link below.....I hope it works.

Thai-English dictionary

Or the rather good dictionary here, or if you get stuck, ask someone here to translate for you.

Check this out. Im trying to download it now.

right Mighty Mouse ...

the best so far

I use this one too, and my wife said, "it's ok, looks better that what I can do"

a good thai-english online one ...

but if you plan to translate english into thai, you better check it by some thai friends, for a final touch, and correct some little missinterpretations ...
