as you can see, the IDE preferences window is much wider that before. Responsible for this is most likely the page displayed below, where the "theme support" checkbox has a very long text.

I don't know how it was layouted before, but i propose to put the checkbox to a line of itself.
Here is a sample how the other pages now look like:

Btw, it would be great if the treeview could get 150 pixels more in width.
