I have a pretty new Win 7 pro 64 bit system. I have set the machine up to use the included fax utility. Usually it works as expected. More often, however, I get a message...as the program is closing...that "the remote fax machine did not respond in time and the call was terminated." Most of the time (so far, every time) the fax goes through and is received on the other end. But the error message is worrisome and, more importantly, the fax utility will not store the fax in the "sent items" folder. It has had this problem since nearly the day I received it. I have not added a lot of programs to the system yet. In other words, this is not a cluttered or overloaded system. I run virus software (Microsoft Security Essentials) and occasionally a malware scanner. Any thoughts?
