I had installed Windows Vista on my system. The probelm is that when ever i try to double click on my XPS file, it automatically gets open up in the default web browser i.e. Mozilla Firefox. As there are no Firefox plugin on my system, as the browser automatically asks me to save the file on my pc. Can any body tell me that why i'm having such problem on my pc? Does any body knows about this issue? Kindly help me out to resolve the above issue.
