Buttons and separators placed on a captioned toolbar are obscured by the toolbar caption when the toolbar is set to fullsize.
Steps to reproduce:
1. Drop AdvDockPanel on form
2. Add an Advtoolbar to AdvDockPanel
3. Set Advtoolbar.fullsize := true
4. Add a button to the toolbar and given the button a caption
5. Give the toolbar a caption and set advtoolbar.showcaption := true
Result: Button is obscured by the caption
Comment: problem is related to advtoolbar.fullsize; problem goes away when advtoolvar.fullsize:=false
