How the error may be repeated step-by-step?
TsSkinManager is activated?
Yes TsSkinManager is active.
1. Create a new VCL project in the Delphi Berlin.
2. Place TsSkinManager on the form and set SkinDirectory and SkinName properties. And set ScaleMode to smVCL.
3. Place TsSkinProvider on the form.
4. Place TsDragBar on the form.
5. Place TsSysButton on the TsDragBar.
6. Run the project by pressing F9 key.
When I run it, It gives an error (see first post screenshot) and when I click the Break button on the debugger exception it shows the GetClientOrigin function of Vcl.Controls unit.
