Hey, the author still exists (better link than above).

SWMBO was complaining that xv "grab" doesn't work properly in Ubuntu 10.04. So, we just spent an hour together poking through it, and fixed it with this one-word change to the sources:
Code:

+  if (!autograb) XGrabButton(theDisp, (u_int) AnyButton, ButtonPressMask, rootW, False, 0, 
                             GrabModeAsync, GrabModeSync, None, tcross);
   
   if (autograb) {

SWMBO has emailed the change to the author, too.

Cheers
