Possible to prevent conversion to smilie

[Snowhog]

How do we prevent vBulletin from converting typed text into a smilie?

When the number 8 is immediately followed by the ) symbol, it gets converted to a smilie.

Example: Version (2.00138)

In our vBulletin 4.2 forum, the above gets rendered as:

Version (2.0013

As is indicated here in Additional Options > Miscellaneous Options, we also have Disable smilies in text unchecked.

What do I need to look for to 'fix' this?

Thank you.
