commit fc6c07c385c08b503512481b996fe404faaf7092 Author: Giannis Adamopoulos <[email protected]> AuthorDate: Thu Nov 23 23:07:35 2017 +0200 [UXTHEME] Add a hack for themed scrollbars - After inspecting a theme file with different upper or lower tracks it seems that windows use what is called LowerTrackHorz and LowerTrackVert in the upper track and UpperTrackHorz and UpperTrackVert are used in the lower track.
