It would be very helpful to see the original message on the screen when replying to pms rather than have to open a second window and keep toggling back n forth to answer questions in Pm's.

Also it would be nice to have the Do you wish to leave this page?, warning before the action in cases where a button is pressed inadvertently or when a person spaces out and try's to close the browser or window. I've lost some really long replies this way many times.
