You can drag the bottom bar up if it is minimized, well you should be able to.

Please try at your own: right click drop down menu "Configure Movie Filters" -> uncheck all checkmarks filter options. Can you get the right click drop down menu "Configure Movie Filters" back? 

Ok, can't drag the bar up, as no filter is selected to fill the void.
But, can move the mouse between the filter bar and bottom bar, and right click to bring up the Configure Movie Filters box to re-enable filters.

 

One way to fix that would be to make general un-selectable.  You can still drag the bar up or down.
