I have about 5 mdb files that contain programs and data, links to data, etc. that I have been using for years with Windows 98, Access 2000. After a few months of fine tuning, everything worked without problems when I switched to Windows XP, Access 2002.
Suddenly, when I open any of these modules and compile any new code, I receive the error "Runtime Error 2455", "You entered an expression that has an invalid reference to the property "xxxx". (The "xxx" usually being the first referenced after opening the module - e.g.: .visible, or the use of a function as Time(), Date(), etc.) Sometimes the "xxx" refers to a property that I'm not even using in the code.
