FilterParams doesn't like scrolling through Categories of filters

Quickly scrolling through the Categories pop-up menu (with a wheel mouse's roller wheel button) generates an error.

(Had just noticed that the wheel mouse roller scrolls more than the scrollbar area indicated by the mouse pointer. So was trying scrolling while indicating different GUI elements. This time was is the Categories pop-up menu indicated in the FilterParams dialog.)
