As I remember it is quite easy to move it around the screen. Can't you just move it outside it? Code will look like oCGameInstance.hpBar.zCView_vposx = 99999.
I have no idea which oCViewStatusBar member is responsible for position on the screen, from their names I can guess that it's either zCView_vposx, zCView_pposx, zCView_px1, zCView_px2, zCView_winx, zCView_posCurrent_0 or zCView_posOpenClose_0 and their 'y' pairs.
