// HMD Tabs V 1.03 2003-02-12
// C. DI Meitz Helmut, 8042 Graz
// 
// History
// 
// 2003-02-07 Item 5 in HMDTabItems added, used as target. If blank, default target is used
//            
// 2003-02-10 HMDTabsStylePrefix eingeführt
//            HMDTabLeftStartOffset und HMDTabTopStartOffset eingeführt
//
// 2003-02-12 HMDTabsStylePrefix geändert, wird jetzt nur mehr für Text verwendet
//            RR_BG und RO_BG auf 200px verbreitert (wg. Netscape)
//            Class=TabText nicht mehr verwendet, daher kein css mehr notwendig
//            Images liegen jetzt in ../types/tabs/images und verwenden HMDTabsImagePrefix
//

// Ausrichtung von links
