Display issues when moving a susbtitution beyond listbox limits in substitution group editor

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Create/Use "Substitution group editor" page more than one screen long 
(resize the screen smaller if you want to cheat)
2. Select a line (it will turn blue)
3. Use the keyboard shortcut to move it down the list (it will turn grey)
4. Keep going down beyond the bottom of the window

What is the expected output? What do you see instead?

The window should scroll as you move down beyond the last line but instead your 
line disappears from view. When you then move it back up into view the line is 
not highlighted at all. 

What version of the product are you using? On what operating system?

FoxReplace 0.15.0, Windows7

Please provide any additional information below.

The "Foxreplace options" window behaves as expected but not this "Substitution 
group editor" sub-window.

It also happens using the buttons instead of the shortcuts. The implementations 
in both windows are different, that's why it works in one place and not in the 
other.
