It's not supposed to move.  Why should it?

However, reading between the lines, I wonder if you're having trouble
getting the input focus to shift to the new window.  This would be the case
if you had NoTitleFocus set (in your .twmrc file for example) or if you were
using a "click-to-focus" window manager like mwm.

I'm afraid there *is* a bug that pops up when Epoch is used with tvtwm
(I use a SUN sparcstation ELC).  I noticed that the cursor decides
randomly whether or not to notice a change of keyboard focus caused by
a keypress.  (The <End> key throws a window to the background in my
instalation.  I have several virtual screens where the mode-line of an
Epoch screen overlaps with the title-bar of an Xterm.  I position the
mouse pointer in the overlapping area and switch focus using the <End>
key.  I noticed that Xterm always shows the right cursor.)

Furthermore Epoch sometimes fails to notice that I switched virtual
screens.  In those cases I don't see a cursor at all, and keyboard
input goes to the previous Epoch screen.  Both anomalies can be
corrected with a click, but the random factor is quite annoying.

Actually, I think this is a bug with (TV)TWM --- I've experienced it
intermitantly, but only when I use epoch without title bars! I think it's due
to TWM not sending the correct focus events, and other applications don't
experience this by looking for EnterNotify and LeaveNotify events.

Well, I've been experience this problem too, but in a different
flavor.  I'm running epoch ( with title bars ), and my screens all
receive the proper focus in response to mouse movements except for in
one case:  when I use the f.warpto function of twm to warp to an epoch
screen.  In this case, the screen does no receive keyboard focus, and
I need to click the mouse to get proper focus.  

So, I don't think it has to do with title bars, but probably does have
with epoch's monitoring of EnterNotify and LeaveNotify events.

I think Epoch is not a very nice X application. It is not using Xt and is
having a strange input mechanism. So it is possible that in certain situations
it is loosing event. 

But we also had focus problems using Epoch and twm. These problems disapeared
using Mwm. Mwm is garanteed to be ICCCM compatible, twm is not. 

Conclusion: both can be wrong, but my experience points in the twm direction:
try another window manager.

That doesn't make it a bad X application, if it does what it does
correctly.

   So it is possible that in certain situations it is loosing event.

   But we also had focus problems using Epoch and twm. These problems
   disapeared using Mwm. Mwm is garanteed to be ICCCM compatible, twm
   is not.

It's almost certainly the window manager's fault.  I've been using
Epoch 4.x under mwm and derivatives, and even tvtwm, constantly for
two solid years now and I've *never* seen a focus problem.

Cheers,
Marc

$0.02=
I tend to agree - I've been using with gwm with no apparent focus problems...
