Hello,
using HTMLPopup 1.4.2.1 with Delphi XE3 following bug happend:
ShadeEnable = true;
ShadeEndColor := clSkyBlue;
ShadeStartColor := clBtnFace;
ShadeSteps := 40;
=> Instead of clBtnFace there is a very dark color (maybe even black) used. This happens allways when a non standard color (as clRed, clWhite) is used. So it seems at least.
When I use an own TColor value this also happens.
