First of all thanks for the great work that you do.
I have one problems on the frozen columns on IE 10 (Yes on IE10 damn) and another general.
1) On IE 10 when I go in the bottom of the grid ( Also in your example of showcase of the "Frozen Columns".)
the last row is not aligned, and this shift all the rows up of some px.
2)For the general one , the mouse Wheel is not working on the left part of the grid in all the browser .
Do u know if there is some solution ?
