xwd : capture window on linux

xwd is the basic tool to do screen (or window) capture. I used it in my xw manager fvwm2. Here is a shot, but it seems not dump the title part of the window (gvim). Would like to find out the reason.

fvwm - newbie for the years

I find myself newbie on many things such as cvs, fvwm even I use them for a long times.
On Fvwm, although most people use gnome or kde, but I am still get it a try. I like it simple, not cost too much memory. In spare time, I am fiddling into FVWM, and at last I figure out the set up of "micro GUI" decor.
