for some reason since i updated to 1.3 my gsx menu will not show up when i load the  757 PW or RR varient ... iv tried re- installing the 757 with anti virus off etc .. iv uninstalled and re insalled gsx .. the problem seems to lie with the 757 as the menu with gsx works fine with all my other add-on aircraft but as soon as i try to load in to the 757 gsx just simply does not work with it :o :(
