Ok, i write in VB, but I noticed that in C# it doed not give a very good 
error... just 
Attempted to read or write protected memory

so i recreated it in VB, and got the same error but more information, the list 
box
contains to many items?!?!?!? well after a little playing and testing...

in Style.cs
comment out the overrides ToSting
add property StyleName
and just do a get name
NO SET for this

on the SettingsForm.cs
in SettingsForm function (the NEW function for VB)
where you see the lbStyles.selectedindex = 0
right above that add lbStyles.DisplayMember = "StyleName";

problem solved

Hi.

Found this one out and it appears that tha problem happens in some files rather 
than
others, due to many styles with null names.

To solve this, instead of commenting out the ToString() override, you can just 
add
something like 

        if (string.IsNullOrEmpty(s.Name))
          s.Name = "Style " + i;

in the constructor of SettingsForm, so that it will give unique names to the 
unnamed
styles.

And trsprayp, cheers for finding out about the listbox! I was bangging my head 
around
this one, and if it were not for you, I'd still be.
