Thank you for your replies.
Still nothing happening. When I left click on the arrow next to the paper clip or the Attachments button following the post window, I get nada.
Its as if the Forum is blocking my attempts to add an attachment, but the Forum Rules window under the post window states that I may post attachments.
I must be doing something wrong, but don't know what.
