File in use problem.

I have used Visual Basic 6.0 to write an ActiveX DLL. Once the DLL has been compiled and saved I then use my browser to load and ASP pages that uses the DLL. I am using Windows 98, with Personal Web Server. Everything works fine.

My problem is that I then change the code for the DLL and try to remake it and get a permission denied as the existing file is in use. I have tried closing all the applications (including start/stop PWS) that I can think may be using the file and it is still reported as being used. The only way I can overwrite the DLL is to reboot my machine. This is obviously not the right way to do this. Can anyone please help me.

Thanks in advance.
