rxvt

[Michael Symalla <msymalla@mail.desy.de>]

Dear Debian-Experts,

i have changed all my xterms against rxvt because it looks nicer with
the scrollbar and the colours (for example in pdmenu). But when I have
opened to much rxvt's I can't open anymore, the only message I recieve
is

rxvt: can't open pseudo-tty
rxvt: aborting

So, how can I change this or does anyone know a good xterm replacement
with the properties mentioned above?
