When mouse enters fpGUI application, the application can enter endless loop of processing the paint messages.
The issues can be fixed by adding line "FInvalidated:=True;" in procedure TfpgWidget.MsgPaint at line 1577 before "for i := 0 to ComponentCount-1 do" in src/corelib/fpg_widget.pas.
This might also resolve issue #111.
