Yes - I am using same and get same. I run by right-clicking script task and execute. I also see Orange next. However, to see the next two dialogs, I have to click on icon that is in taskbar. See part of code below:

For Each value In MyList

' Dim button As DialogResult = MessageBox.Show(New Form(), value.ToString(), "ArrayList Value " + i.ToString, MessageBoxButtons.OK) 'this works

Dim button As DialogResult = MessageBox.Show(value.ToString(), "ArrayList Value " + i.ToString, MessageBoxButtons.OK) 'this only shows first two dialogs - then have to click on taskbar icon to see next two dialogs

i += 1

Next

BTW: it works fine in debug mode - but otherwise, have this problem with
