Vertical Scrollbar in Main Chat window

[fubaerra]

I have made the chat input font size bigger as well as the text box and channel button at the bottom of the main chat window. However, i would also like to increase the (horizontal) size of the vertical scroll bar so it matches again with the channelbutton.

I have added the appropriate Rectangle styles in /CommonElements.ScrollbarVertical.data for the Default, Pressed and Disabled states in for example the following way:

<RectangleStyle Name="rect_bkg" Center="bkg" CenterShrinkH="true" CenterShrinkV="true"> (Is this correct?)

How do i add these RectangleStyles to the ScrollbarStyle to make it stretcheable, or am i going about this completely wrong? : )

Thanks!
