Hi, It is strange to me that lyx can not paste (middle-button) its own selection, since it can paste selection from other application, and other application can paste lyx' selection. I traced a little bit in text3.C, and find that the selection will become empty if a single click is executed. That is to say, a click would be considered as an empty selection that removes previous selection. The consequence is that when a user locate another place with a mouse click, then use middle button to paste, there is nothing to paste.
What do you think about this? I think the better behavior is that empty selection should be silently ignored so paste would paste previous meaningful text. I could not locate where and how to change the current behavior though. Any help is appreciated. Cheers, Bo
