8.1 Communications Applications For best results when running a non-Windows communications application in the background, run it as an icon instead of in a window. Also, create a PIF (program information file) for the non-Windows communications application (if one does not already exist) and do the following: . Select the Execute: Background check box. . If you encounter errors during file transfers while running the application in the background, increase the Background Priority option in the Advanced Options dialog box. . If you use a permanent swap file with 32-bit disk access, select the Lock Application Memory check box in the Advanced Options dialog box. For information about using and creating PIFs, see Chapter 8, "PIF Editor," in the Microsoft Windows User's Guide. .
