I have an application that uses the SSTab control extensively. There are tabs embedded within tabs. Every time I make even the simplest change to the controls within these tabs, the tabs will not display the proper information. It appears that when some of the tabs are selected the wrong controls are displayed or no visible change occurs. It seems that the tabs have lost their way. I am at wits end trying to correct this situation. In some of the simpler cases I simply cut the controls in the tab and repaste them. This appears to work but the tab controls embedded within tab controls do not response to this technique. I am at this point stuck with the tab control as rewriting the application without them would be impracticable
