Thanks for the confirmation. Only a second before reading your
email, I had it happen: I had two Netscape pop-ups one above the
other, with the focus on the top one. I hit escape to close the top
one, and when it went away, focus was not in the bottom one (even
though the pointer was). I may have been moving the mouse at the
time. Moving the pointer into the title bar gave it focus.

I just reproduced it once using the suggestion you gave (moving the
mouse while switching pages with the keyboard), though it's not
consistent. I also reproduced it on the same machine using an
unmodified X server and gpm. My technique was to open two xterms,
put the focus in one, and close it with ctrl-d while moving the
pointer into the other. Sometimes, when I get to the other, it
doesn't have focus. I'll try reproducing on other machines.

Anyway, I'll write this off as a known problem. Thanks!

Well, the machine where I see the problem is the fastest of the
bunch, however it is using the unaccelerated framebuffer server,
which obviously makes many drawing operations slower.
