... it shows up as this ...

The end bracket does not get counted as part of the URL. Maybe a condition could be set so that if there is a "(" before http, https or www, then a closed bracket will not be accounted as being a part of the URL at the end. But if there is no bracket before http, https or www, then the bracket will be counted as part of the URL at the end.

The current simple fix is to add the [url] bbcode.

I'll let you guys decide what's best.
