I'd be suspicious of the video drivers perhaps Xlib (xterm, rxvt?) is triggering some bug in the video driver that Qt (Konsole) isn't. qterminal is another Qt-based terminal emulator that might confirm whether the widget set is having an effect.
no problem with qterminal I've now the proof that fvwm is not involved: I could reproduce the problem with fvwm not running (it's a little acrobatic, as you loose the focus after killing fvwm, and must use the mouse to run a command...) So, may-be a bug report would be justified, but against what: xterm / X.org video driver / libx11 ...? best regards, -- Pierre Frenkiel
