Ok, had some time and figured out what was going on. It's a very simple fix so I will not be resubmitting the UI with the change. Instead, I will explain how to fix the problem and the fix will of course be included with the next update.
-Open your Oink!_Reborn folder.
-Right click on UI_CastSpellWnd
-Select
Edit (or select
Open With and then select Notepad or a similar program)
-Scroll down towards the bottom of the page, line #541
-Delete Line 541 through Line 548 or to be more specific, this chunk of code
Code:
<Screen item="CSPW_ScreenSpellBook">
<Size>
<CX>40</CX>
<CY>22</CY>
</Size>
<Pieces>CSPW_SpellBook</Pieces>
<Style_Sizable>false</Style_Sizable>
</Screen>
-Go to the bottom of the page and delete line #619 or to be more specific
Code:
<Pieces>CSPW_ScreenSpellBook</Pieces>
-Go to the bar at the top, click File, then click Save
That's it. Easy fix. Sorry for the mess, I added those lines during the Underfoot pre-release and never really tested. My apologies.
