I seem to be having a problem posting a response to this thread. click here Every other thread I have posted a response to works fine, except this one. Every time I click on post response I get "Error Ocurred, You have accessed this page incorrectly etc...."
I have finally sent the response by email direct to the poster, but that means it is not there for everyone else to see.
You are not alone. Both VoG and I have had this problem (and probably others too).
I have found that one particular thread would only accept a response if I broke it down into single lines - anything larger would result in a 'page not found' error.
Another thread would not let me post anything at all for a few hours - then suddenly, after a few others had made postings to that thread, it became 'unlocked' for me, and I could post a multi-paragraph message without difficulty.
I sent several messages to the moderator, but have had no acknowledgement or explanation, so like you, I am still puzzled.
