I'm going to make an assumption (I know that's a dangerous thing) and take a guess on how to do this.
If you open your templates file, search for RoundedNoTitle
Replace this section of code
Code:
<Border>
<TopLeft>A_RoundedFrameTopLeft</TopLeft>
<Top>A_RoundedFrameTop</Top>
<TopRight>A_RoundedFrameTopRight</TopRight>
<RightTop>A_RoundedFrameRightTop</RightTop>
<Right>A_RoundedFrameRight</Right>
<RightBottom>A_RoundedFrameRightBottom</RightBottom>
<BottomRight>A_RoundedFrameBottomRight</BottomRight>
<Bottom>A_RoundedFrameBottom</Bottom>
<BottomLeft>A_RoundedFrameBottomLeft</BottomLeft>
<LeftTop>A_RoundedFrameLeftTop</LeftTop>
<Left>A_RoundedFrameLeft</Left>
<LeftBottom>A_RoundedFrameLeftBottom</LeftBottom>
<OverlapLeft>0</OverlapLeft>
<OverlapTop>0</OverlapTop>
<OverlapRight>0</OverlapRight>
<OverlapBottom>0</OverlapBottom>
</Border>
<Titlebar>
<Right>A_Filigree3TitleRight</Right>
<Left>A_Filigree3TitleLeft</Left>
<Middle>A_Filigree3TitleMiddle</Middle>
<OverlapLeft>0</OverlapLeft>
<OverlapTop>0</OverlapTop>
<OverlapRight>0</OverlapRight>
<OverlapBottom>0</OverlapBottom>
</Titlebar>
With this
Code:
<Border>
<TopLeft>A_InnerFrameTopLeft</TopLeft>
<Top>A_InnerFrameTop</Top>
<TopRight>A_InnerFrameTopRight</TopRight>
<RightTop>A_InnerFrameRight</RightTop>
<Right>A_InnerFrameRight</Right>
<RightBottom>A_InnerFrameRight</RightBottom>
<BottomRight>A_InnerFrameBottomRight</BottomRight>
<Bottom>A_InnerFrameBottom</Bottom>
<BottomLeft>A_InnerFrameBottomLeft</BottomLeft>
<LeftTop>A_InnerFrameLeft</LeftTop>
<Left>A_InnerFrameLeft</Left>
<LeftBottom>A_InnerFrameLeft</LeftBottom>
<OverlapLeft>0</OverlapLeft>
<OverlapTop>0</OverlapTop>
<OverlapRight>0</OverlapRight>
<OverlapBottom>0</OverlapBottom>
</Border>
<Titlebar>
<Right>A_WindowTitleRight</Right>
<Left>A_ChatWindowTitleLeft</Left>
<Middle>A_WindowTitleMiddle</Middle>
<OverlapLeft>0</OverlapLeft>
<OverlapTop>0</OverlapTop>
<OverlapRight>0</OverlapRight>
<OverlapBottom>0</OverlapBottom>
</Titlebar>
Let me know if that works.
