Hi Danny,
that is no Problem of SiDiary, that´s normal for Programs on Pocket PC. If you use X to close the running program,
the program will be only put in Backround. You can realy close SiDiary if you use the Backdoor Button on the register (c) Copyright.
You can use the Taskmanager too, or there are programs to handle it e.g. WisBar Advance.
