When I start Excel 2007 a couple of files load at startup (Common
Macros.xlsm and Personal.xlsb) both of which contain macros.  Everything has
been working fine for quite a long time but today I get "Compile error in
hidden module: This Workbook".

I have unhidden both the files and restarted Excel.  Common Macros.xlsm
seems to load ok but I get the above message immediately after that, so I
assume the problem is in Personal.xlsb.  I am unable to tell which module is
causing the problem - is there some way of finding out which one?
