WinForms: Why does my tooltip never come back?

Question

I'm having a problem getting the tooltip on my form. Once it disappears it never seems to come back!

Excerpt from the InitializeComponent method:

// 
// toolTip
// 
this.toolTip.AutoPopDelay = 60000;
this.toolTip.InitialDelay = 500;
this.toolTip.ReshowDelay = 100;

After the InitializeComponent method has been called:

toolTip.SetToolTip(control1, "text");

Firstly, if I hover over the control1 control I see "text" in a tooltip for 5 seconds, regardless of what I set the AutoPopDelay to. I've even tried setting it to Int32.MaxValue.

Secondly, if I let the pop up show for 5 seconds, after it disappears it never come back. If I move the mouse or something before 5 seconds has passed the tooltip will come back as expected if I hover over the control again.

Has anyone had and solved these issues before? I don't seem to be able to find an answer to this specific problem online.

TIA

About the delay time:

From http://msdn.microsoft.com/en-us/library/system.windows.forms.tooltip.autopopdelay.aspx

The maximum time you can delay a popup is 5000 milliseconds. For longer durations, use the Show method to control the exact moment when the ToolTip is displayed.
