I traced where the name originates.
sStrings.rc s_AvailSkins, “Available skins”
sConst.pas acs_AvailSkins := LoadStr(s_AvailSkins);
sSkinProvider.pas SkinItem.Caption := acs_AvailSkins;
Curious why you were not able to append they system menu and had to do it differently. If you had used append the menu I could have found the menu item and changed the caption to whatever I wanted to call it like
spMain.SystemMenu.Items.Find('Available skin').Caption := 'Available style'; However, it does not find it since it is not a system menu item but it does reside in the system menu. My head is spinning.
