Strange, I fixed this problem by commenting out the line where the DoubleBuffered property of the TJvTabControl was set to true, now the error has disappeared. Should this be considered a bug? |

Could you check the version of JvExComCtrls.pas. It should be: // $Id: JvExComCtrls.pas 11407 2007-07-05 17:11:35Z ahuser $ With this version you should not get an error if you execute: JvTabControl1.Perform(WM_ERASEBKGND, 0, 0); |

No news, I'm assuming this is fixed |
