Very odd whs,
I copied the lines from your script box and pasted the in this post. I'm still on IE 9 though.
I don't know why you have the extra BBcode tag (FONT), but have seen the forum do some automatic "fixes" on some post or templates. It seems as though there is a strict order for tags - break it and it gets "fixed"
I notice this most if I copy a URL in a post and paste it above or below the orginal placement. I get extra tages for COLOR and UNDERSCORE - sometimes BOLD gets screwy and then the titles aren't retrieved from the URL.
Try this as an exercise: Edit your post# 1 and click on the editor button in the upper right hand corner of the post window to switch to the basic editor and display the BBcode tags. It looks as though there might be a (FONT) tag stuck between the (URL) tag of the first example.
Looking at the link on post# 1, when I mouse over the text and image "link" I see http://[font=calibri
Both links in this post take me to the desired location.
I don't know what to tell you, other than to preview posts and fix any anomolies with the basic editor.
Or.... you could use a different browser
