MsgBox or MessageBox.Show doesn't show.

Hello,

I need help displaying a MsgBox (I know this sounds pathetic, but read on).

When I try showing a MsgBox using the MsgBox() function, I just get nothing.

But, when I try showing a MsgBox using the MessageBox.Show() function, it returns that the default button was pressed. However, the messege box didn't show.

This is a Windows Forms app that is started by a service. NOTE: When I start the app by itself, everything works fine.

Environment: Microsoft Visual Studio Express 2012 for Windows Desktop with the target framework set to 4.0.

Maxwell.
