Tooltips and Multipane charts

A very vague and general question:  "Are there any issues with tooltips and 

multipane charts?"

I am attempting to better determine the precise scenario which is causing us

problems and will likely have more information tomorrow.

For now:

We are running into unhandled exceptions with the following stack:

12/18/2006 3:06:35 PM Object reference not set to an instance of an object.

at ChartFX.WinForms.ax.d(Boolean A_0)

at ChartFX.WinForms.ax.a(Int32 A_0, Int32 A_1, Rectangle A_2, HitType&

A_3)

at ChartFX.WinForms.ah.f(Int32 A_0, Int32 A_1)

at ChartFX.WinForms.ah.a(Point A_0)

at ChartFX.WinForms.b.a(Object A_0, EventArgs A_1)

at System.Windows.Forms.Timer.OnTick(EventArgs e)

at System.Windows.Forms.Timer.TimerNativeWindow.WndProc(Message& m)

at System.Windows.Forms.NativeWindow.Callback(IntPtr hWnd, Int32 msg,

IntPtr wparam, IntPtr lparam)

We have a form which displays data in line, bar, and pie chart formats.

We use a combo box to determine which format to use.

We rebuild the datasource whenever we switch formats.

The OnTick above makes me suspicious that this is happening after the

tooltip delay.

Still trying to get the problem(s) to be reproducible...

Any thoughts greatly welcomed....
