In the Control Browser under "ToolTip Title Color" the functions are listed incorrectly
They are listed as:
(dcl_Control_GetToolTipPicture <CONTROL>)
and
(dcl_Control_SetToolTipPicture <CONTROL> NewValue [as Color])
I think that they should be:
"dcl_Control_SetToolTipTitleColor"
Good catch. This is now fixed for the next build.
