Preventing size_allocate event from label widget?

[The Surprises <thesurprises1 comcast net>]

I have a label packed into a Frame, which is packed into a table.  It is
a counter that tracks the mouse movement.  Whenever the label changes,
it causes a size_allocate event on the entire table (which subsequently
refreshes my draw routines).  Is there any way to prevent it from causing a
size_allocate event?

Thanks
