In a program I have recently been writing, there is now a reference to DIRECT ANIMATION LIBRARY (DAL).The program was written under 98SE/2000.

I do not know (remember) how this reference came to be added, and can not find out what it is, what it does or why it is there. But the program code was running satisfactorily with it called up.

When we came to running the code at the design stage under Vista64, errors were generated related to DAL.

So I thought to delete the DAL reference from the project on the 98/2000 development machines to see if it was necessary.

However on opening the project, going to references and attempting to un-check DAL I get the error message "Can't remove control or reference in use".

So questions are please :

1. What is DAL and what does it do/interact with?
2. How can I force its removal as a reference to see if it is serving any useful purpose?

Suggestions appreciated.
