Hi Nick,   
  
 No this is not a bug, it is a compatibility feature of Windows when running a 32-bit application (FinalBuilder is 32-bit) on a 64-bit version of Windows.   
  
 More technical information can be found at: [http://msdn.microsoft.com/en-us/library/aa384274.aspx](http://msdn.microsoft.com/en-us/library/aa384274.aspx)

 Paul.
