title block & bom issue

There are three of us here that seem to be having anidentical problem, that none of have had before sw 2009.
We use an excel based title block & bom. None of us can see apattern, but occasionally solidworks will freeze when we attempt toedit in excel.
We all have sw 2009 sp1; excel 2003 sp3 and run xp sp2
Has anyone else experienced this problem, and have you found a fix?
Thanks to all for you help.SolidworksDrawings And Detailing
