What is the declaration of FrameBrowser? Is it an LCL control?
This is a part of THTMLViewer/FrameViewer component: FrameBrowser: TFrameBrowser;
TFrameBrowser = class(TFVBase)
TFVBase = class(TFrameViewerBase)
TFrameViewerBase = class(TViewerBase)
TViewerBase = class(ThtControlBase)
ThtControlBase = class(TWinControl)
TWinControl = class(TControl)
TControl = class(TLCLComponent)
