I am using a webbrowser in delphi program to open MS word (ver: 2002 or 2003) documents.
Sometimes, i got "interface not supported" error message. Once this happened, the doc cannot opened, i have to kill winword in task manager, then try again. Or sometimes, I just try to open some other doc, and it just works and open the previous one, it also works.
Why this happened? how to fix the problem permanently?
