Checkbox in Listbox App on Window 7

Hi, Guy
I would like to build the desktop application, My component have listbox with checkbox on cell. I test the code on Window 10 and OSX, It’s work both!
But on Window 7 the checkbox it seem disappear, So I try to click on area that should be checkbox then it’s blink the checkbox in second and disappear again.
There are any solution to make it work on Window 7?
Thank you

Here my code, it activated when event “open” occur

		Self.Listbox1.AddRow
		Self.Listbox1.ColumnType(0)  = Self.Listbox1.TypeCheckbox
		Self.Listbox1.CellState(0,0) = Checkbox.CheckedStates.Checked

Make sure you have the optional update KB2670838 installed on the Window 7 machine.
