xv causes system lock

[Steve Merrifield <sjm@livewire.ee.latrobe.edu.au>]

Hi,

I've just installed hamm, and I have a strange X problem:
Both xv and imagemagick lockup the system when I try to use
the menus. I can display images okay, and can use the keyboard
shortcuts, but using the pulldown menus causes the system to halt, 
requiring a reboot. Other X programs like Netscape, xfig, gv etc 
are fine. Seen this before?
