Need to remove sort arrow above vertical scroll bar on listgrid

[cjustice]

We would like to remove the sort arrow that appears above the vertical scrollbar when column(s) are sortable on a ListGrid. Is there a call on the ListGrid object to do this?

See the attached jpg to see a visual picture of what I'm asking for.

Thanks!

ListGrid.setCanSort(false) removes sort arrow, but if you still need user defined sorting in grid, then I have no idea.

See setShowSortArrow()

setShowSortArrow(SortArrow.FIELD) just about does what I want, but it does have a significant draw back in that if you right mouse click above the scrollbar where the sort arrow used to be, you know get browser options. Is there a way to turn that off?
