UseMnemonic property of Labels is giving me a problem. I am displaying one line of text from a database. It could contain a "&" and I do not want that replaced with a "_". I first tried the following: Label1.text=rStrReplace(text,"&","&&") That was fine but I thought it would be better to just use the Door Library to set UseMnemonic to false: Door.FromControl("Label1") msgbox(Door.GetProperty("UseMnemonic") Door.SetProperty("UseMnemonic",false) Using either of the last 2 lines will cause a NullReferenceException error. I'm using my previous code to get around this so just reporting my error.
