Normal/expected behaviour is to prompt if it's changed when you switch to/activate the tab/window/edit box. This allows someone to keep an "unchanged" or scratch copy in one window while editign the other. If they're for a split edit feature (i.e. Visual Studio's split editor) then what you ask is fine, but I don't knwo how to do it. – Deanna Aug 08 '11 at 13:40

If you are using CPropertySheet and CPropertyPage for multiple-tab support, you may override CPropertyPage::OnSetActive and CPropertyPage::OnKillActive. Set the current text in OnKillActive and set the same text for other tab that is going to be active (in OnSetActive).

Sorry doesn't work because in one case they can be even on the same page. – Lothar Aug 08 '11 at 04:25
