rxvt-unicode also has some of the best (most accurate, most complete) terminal emulation out there, second only to xterm. Daemon mode is also a neat trick if you're running on a limited-memory system.
I don't have that problem. Perhaps there's something glitchy about the way rxvt-unicode works with your setup in particular -- which might be an rxvt-unicode problem, but not a problem that affects me, evidently.
