If so, I've just posted a test reply to your last post and it seems OK. Not locked. My reply here;
We are close to the 12 sub-thread post limit there, but not yet.
I received an email informing me of a new post to my thread, I clicked on the link taking me to it, I signed in, tried to post a reply but couldn't. I clicked on reply and nothing happened. Usually I'll hear a click when I click on reply but nothing. My thread was in the Windows Vista forum, has it been locked?
