Design Table error in Solidworks 2010 SP5.0

Hi All,

Sometimes when I create/edit a design table. The message below pops up.

Also another colleague who has the Solidworks 2011 SP3.0 has encountered the same issue.

I run Windows 7 Pro SP1.0 64bit and the other person runs Windows XP SP2.0 64bit

Thank you

Neil
