in Design Time
in Run Time
I use TMS VCL UI Pack V10.5.1.0 in Delphi7, Delphi6.
They have problem in DesignTime, The Picture of AdvSmoothButton is not shown normaly.
Windows10 64
This is potentially related to the old Delphi 7 IDE, it is working as expected in any newer Delphi version.
We put this on the todolist for further investigation.
