This is moving beyond annoyance
Throughout Lion I had to deal with this and it is continuing.
Suggestions to use a different terminal emulation program will fall on deaf ears as none of them are as fast (scroll wise) or as compatible (vt102 is not the same as vt100 or vt220), nor look as nice (anti-alias much SecureCRT?).
Gah, I am so frustrated with this continued PoS that is the resizing of my Terminal.app windows.
See my previous rant.
