Hi All,
Let me just say I dont want to start a flame war or anything with these comments its just my sense of homour. If you dont have one then might be best skip this post.
Well it seems to me that there is alot of “It’s not our fault, its theres” when maybe the dev’s of these two programs should be saying “lets sort this out”
So far I have the following list of whos at fault here.
OS
Whois.cart
Interworx
and now Zend
and 50% of the world is saying ‘it’s windows’
Have I missed any? 
On the note about the 30+ interworx customers. Alex are you sure they are using the product and have not just brought a licence, found it does not work and moved on?
It seems a big shame that it does not work as I have said before and will say again it fitted my needs, its not complex easy to use. I have also spent time and money with getting it all to fit into my site. And now when its all set and ready to run we have this issue. I asked 2 linux/php experts about this issue and they said they cant even begin to debug it because its all encoded. Its all over my head at the end of the day im just a end user if I was not I would not require interworx / whois.cart
I guess the USA has woken up now and maybe someone from interworx could check somethings and give some feed back, if any of the interworx guys need access to my box drop me an email.
Look forward to the fix 
instead of 100’s of replys to this email
