DirectInput and SetProperty Problem!

Hi There

Iam using DirectInput to read my spacenavigator but Iam having a problem with DIPROP_APPDATA, I use it to define an axis number and all seems to work but when I use GetProperty to check the value I set it returns -1, all other joysticks etc return the value I just set. Both SetProperty and GetProperty return DI_OK. I asked in the makers of the SpaceNavigator forum and they say its a DirectInput problem. Has anyone had any experience with this?

Thanks
Chris

    
            DIPROPPOINTER diptr; 
        
               diptr.diph.dwSize       = sizeof(DIPROPPOINTER); 
        
               diptr.diph.dwHeaderSize = sizeof(DIPROPHEADER); 
        
               diptr.diph.dwHow        = DIPH_BYID; 
        
               diptr.diph.dwObj        = lpddoi->dwType; 
        
               diptr.uData             = aoff + 1; 
        
               HRESULT hr = dev->mDevice->SetProperty(DIPROP_APPDATA, &diptr.diph); 
        
            // Read it back 
        
            DIPROPPOINTER diptr1; 
        
               diptr1.diph.dwSize       = sizeof(DIPROPPOINTER); 
        
               diptr1.diph.dwHeaderSize = sizeof(DIPROPHEADER); 
        
               diptr1.diph.dwHow        = DIPH_BYID; 
        
               diptr1.diph.dwObj        = lpddoi->dwType; 
        
               hr = dev->mDevice->GetProperty(DIPROP_APPDATA, &diptr1.diph);
