Pasting a link, get one extra linked character when you press enter

[Grinder34]

here's an example;

The link i want to paste: http://www.igotasti.com/vBforum/showthread.php?3767-ODBII-codes
and extra text.

See how the "a" is also linked?

It doesn't happen with no "enter" after the link. Example: http://www.igotasti.com/vBforum/showthread.php?3767-ODBII-codes and extra text.

I have seen this happen to me too. Pretty damn annoying haha.
