This situation may occur after you click Open in the Open dialog box (on the File menu, click Open) to open a file from a network location (for example, a network server). During the process of opening the file, you lose your network connection or the network location that contains the file that you are trying to open goes down. During the process of opening the file, your Office program tries to add the file name and the path information of the file that you are trying to open to the Windows recent file list. Because the network location (path) does not now exist, the Office program may run slowly and may appear to stop responding (hang).
Note This situation may also occur if your connection to your network is slow because your Office program has to make multiple queries to the network to obtain the correct file information.
