                                  • Steps to Reproduce:

                                    Run the attached application and press the second button.

                                    Click any tab within the tabbed container and switch the active TabPage


                                Unfortunately, there is no workaround for a standard Windows Forms TabControl as there's a bug inside the MS UpdateFocusedControl method.
                                However, your example works fine with our XtraTabControl.


                                Here is another project which uses the XtraTabControl and has the same problem. Run the application and double click on a dock panel's tab to make it float. The application will hang.
