- First, just because person #1 is finished with the chat doesn't mean that person #2 is also finished with the contents of the chat window. He may want to copy it somewhere, save it for later, etc. Having it suddenly disappear because person #1 closed the chat session on his end is a serious annoyance.
- But worse than that, the effect can be downright harmful. If person #2 continues typing in the chat window, but person #1 closes the window on his end, the keystrokes that person #1 continues to type will be transferred to whatever window takes the focus when the chat window disappears. This could have unwanted, potentially serious implications.
Thank you.
