Immunization Scheduling Process

Today when the scheduled immunization dialogue opened, it was hidden behind other windows and I could not see it, and the flashing icon on the task bar did not alert me to its presence. I have not selected the option to do the immunization in silent mode, but apparently it was waiting for me to make a choice about something before proceeding. When the alloted time for this task in Windows Task Scheduler had finished, the program was terminated automatically without immunizing anything. It seems to me that there ought to be a better, clear means of notifying me of this situation. When immunization procedure opens, the program should do a better job of letting me know about it even when other windows are open and in focus, and certainly I should be advised if the task did not run as scheduled.
