C# Form Doesn't get minimized on microsoft windows when the workstation is locked

Question

In my application I need to minizime to tray (doing stuff like visible=false, FormWindowState = minimized etc.) automatically after some time.

The problem is, that when Windows is locked when this code executes, it doesn't happen (I'm guessing that while Windows is locked all form operations doesn't take place or something)

Does anyone know what can I do?

When your app needs to minimize to the tray, set a flag. When the session unlock occurs, check the flag and, if set, perform the minimize again.

Easiest thing to do, run the time consuming task with help of the BackGroundWorker, so your UI stays responsive.
