The rest of the taskbar is fine it's just the tray area.
I've set centre (true size) for margins.
for the expander/tray. This is how it's displaying (see picture at top)
Taskbar height dimension = 32
Tray Expander height dimension = 30
Tray height dimension = 30 also
Edit: I found out it's because of the tray image, but for some reason it won't accept my transparency. It keeps converting to bitmap
