Easy way to repaint the Form???

I have a Windows form which runs fine. All of the data processing,etc., runs in a seperate thread, so that the GUI remains responsive. So, life is good. However, this application needs to be able to be started when the OS starts, such as after a reboot. So, I have used ScheduledTasks to schedule the application to start when the OS starts (before the user logons...because it is a server, they may not long on for some time). In testing this, when I did finally logon, I could not see the GUI. However, in Task manager under Processes, I could see the name of the .exe. The .exe was not listed in the Applications tab of the Task Manager, nor could you visually see the form, nor could you see any indication in the Windows toolbar(where Start button lives) that the application was running. I checked the tracelog that I had coded to be written to and could see that it was in fact processing, but you could just never see it. Does anyone have a suggestion?? I am fairly new to C# and .NET, and would like a simple solution, but any suggestions are welcome. Thanks in advance.
