I'm new to fvwm, although I used X11 a lot in the previous millenium. I'm connecting from my Win7 laptop to an Ubuntu box with "tightvnc", running tightvncserver on the ubuntu box and TightVNCViewer on the Win7 laptop. I get to the ubuntu box through an intermediate jumpserver, and I have a local port forward so the Win7 laptop can use the vnc port.
In my "~/.vnc/xstartup" file, the last line runs "exec /usr/bin/fvwm". When I run the client and connect to the port, I can get to the fvwm context menu and create an xterm, and from there create other windows. The strange thing is that after I've been working with this for a few minutes, and then perhaps switch the focus to other windows on my Win7 box and then later return to the vnc client window, I find that all I see is a grey fvwm background. I can create another xterm window, and if I do "ps -elf | grep xterm", I see the original xterm window, not to mention other windows that I've created. Also, if I select "Restart fvwm" from the context menu, I briefly see all the other windows that I've created, and then they disappear. I've gone through this sequence a few times now, and it's repeatable. Why might those windows be disappearing? Is this a fvwm problem, or a TightVNCViewer problem?
