I used CheckedListBox in VB.NET 2005.
Assumed I have 35 items in the CheckedListBox to be shown.
The Box size only can show 3 columns at a time with 10 items per column.
That left 5 items to be unseen, out of the box, on the 4th column.
There is an Horizontal Scroll Bar by default in such situtation.

The Problem :
User intend to check item 25 which is located on 3rd column.
But when user's mouse up, the AutoScroll feature of this control will auto
scroll to LEFT to show
the 4th column and worst yet "Check" the item 35 instead.

Can someone advise me how to deal with this unintend action? Thanks
