Steps to reproduce:
1. create a grid that has more than three pages :
1| 2|3 |>
2.Click on >
Result: < 4| 5|6 |>
3.click on 5
Result: <4 is underlined, but only < should be underlined
With default paging skin used, none of buttons is really underlined ( all of them wraped in link tags, but css rulesin dhtmlxgrid.css block underline )
