Request to jwm users to try a little test

http://www.linuxquestions.org – Hello... I'm using Slackware 14.0 (w/kernel 3.8.13) and jwm as my window manager. I've noticed an odd behavior that I believe is caused by jwm. When I open a jpg image with Imagemagick's "display" program. I am ONLY able to use the menus ONCE. That is: if I edit the image (say adjust the the gamma) I click enhance -> gamma and everything is OK. BUT, if I try to select another menu item like file -> save, nothing happens. I have seen this on multiple computers with very different processors and graphics chip sets BUT ONLY when using jwm. Icewm and twm work fine. I've tried bot (HowTos)
