Fixed clicking on MSW slider not changing value with small ranges.

If the range was 9 or less the SetPageSize call would pass a page size of 0, resulting in the value not being changed when clicking on the slider area (outside the thumb). Fix this by at least passing a page size of 1 to SetPageSize.

Closes #1608.
