Create an xptable, load it with objects.. enough so it gets a scroll bar.
hide the form (or, put the table on a tab and change tabs)
resize the form/tab control
show the form, again.
The scrollbar will have its last known position (hovering in the middle of no where) and will not be attached to where it should actually be. Resizing or repopulating the table will cause the scrollbar to snap back into place.
