No comprende as a library witer you want to support as many platforms as possible--you want the code to wok with vc6 and borland, if possible. Hence you have to #ifdef every ADL lookup point in your code. I think some compilers do get ADL when the function is seen *before* the ADL lookup point, but not between the lookup point and the intantiation. I would have to run a new test to be sure of the compiler conformity, though. -Thorsten
