Sometimes the program should be restarted. It can be done automatically at the specified time. To do that, specify the time for restarting the program on the "Program restart" tab in program options "Options->Program options".
You can also set the program to initiate the at the specified time. On some old versions of the Windows NT operating system it could help to avoid the loss of data when the program has been working for a long time without restarting. Please use the "Other->Port restart" tab in port options.
