I am having a nightmare time in meetings with people poking my soft screen with fingers, pens and pencils. One guy even drew on it before I could get the biro away from him. Before I break someone's arm can anyone tell me if there is such as thing as a hard clear screen protector to fit over my soft antiglare screen? I can only find nasty looking soft sticky things that I really don't want to glue to my screen and aren't tough enough to solve my problem anyway. Thanks in advance. PS I am unable to search the forum. In the first place I can barely read the securing codes and even when I'm SURE I've got it right I get an error message, see attachment.
