Sorry to hear you are having problems replying to others. What happens or what do you see when you attempt to reply to others?
As Mark pointed out, would you happen to be experiencing this forum bug:
Let me know so I can look into it.
Thanks for any details you can provide.
I've wanted to reply to the post under my own thread for ages but no matter how I tried to accomplish it, it doesn't let me.
It's this thread here.
I'm trying to reply to R. Proffitt who replied directly to my post.
TIA for any help!
