What could cause my cursor not to change

[Michael Howes]

I have a button, that when clicked runs a possibly long job. So I change the
cursor to WaitCursor
My cursor doesn't change.

I'm developing in C#

The hierarchy of controls were this button sits is deep.

if this matters...

Windows form
with a Panel on part of it
a UserControl shown in the panel
a docking windows manager (Infragistics) on the UserControl
a Tab control in the docking windows manager
and a button on the tab control

What's interesting is each tab on the tab control is slightly
different....but this one button calls the same method eventually....on two
of the three tabs the busy cursor DOES show.....

So what could cause the cursor change to not show up on this other tab?

thanks
mike

I forgot to mention....I've tried

this.Cursor =
this.Parent.Cursor =
this.Cursor.Current =
this.Parent.Cursor.Current =
Cursor.Current =
and
System.Windows.Forms.Cursor.Current =

thanks
