Well, I dug around and actually found a places where it doesn't happen! I've installed ipython in two locations, at home and at work.
At home it is on a Sun Ultra 5 (severance from a dot-com layoff...) running SunOS 5.8, python version 2.2.2, ipython version 0.4.0. It happens when I'm logged into that machine via my WinXP machine using SecureCRT emulating a vt100 ($TERM=vt100 on the sun.) It also happens when I'm logged in on the Sun's console without a windowing system at all ($TERM=sun). It does *not* happen when I start X on the Sun machine and use an xterm under fvwm2 ($TERM=xterm), but it does when using CDE in a console ($TERM=dtterm). It also doesn't happen when I bring up an xterm under a CDE session! It does happen when I telnet from the WinXP machine ($TERM=ansi) into the Sun machine. At this point it looks like it only works properly when $TERM=xterm...
But at work, I have ipython installed for both RedHat 8.0 and Solaris 5.7 and it happens on both those machines when sitting at the RH 8 machine running KDE using xterms (with $TERM=xterm). It does *not* when using KDE's Konsole (version 1.1.3 KDE 3.0.5a-4 Red Hat) ($TERM=xterm) on the linux machine but does when using the same Konsole to ssh into the Solaris machine. The exact same is true when using gnome-terminal (2.0.1) - no clearing when on linux and clears when ssh'd into the Solaris machine (both with $TERM=xterm).
So, in comparing the behavior to the '@clear' command, it doesn't appear to do the exact same thing. @clear clears the screen and puts the prompt at the top of the screen. I'm seeing a cleared screen and then the '?' info from the bottom of the screen. I also tried unsetting my $PAGER and $LESS enviroment vars which didn't seem to effect it. I normally set $LESS=rsiM
Hope this helps, and let me know what else I can do to help debug it. For now, I guess I'll use Konsole or Gnome-terminal with ipython.
