Can't see help window until I select it

Latest release of XEmacs? Does that mean 21.4.22 or 21.5.29?
Is the new box running Vista, by any chance? I don't think any of our
code has been seriously tested on Vista. And I'm sure essentially no
testing has been done on "Windows 7".
When I do something that should show a "help" window, like
"describe-function", the only indication I have that help has been presented
is "Type q to remove help window, space to scroll the help" appearing in the
status area. The help window does not appear.
If I then do "switch-to-buffer", I see that the help window that I requested
is at the top of the list, so I press Enter, and now I have my help window.
There are a number of possibilities. First, XEmacs may think that the
help window is already displayed (eg, in a frame which is obscured by
other GUI windows). Presumably you would be aware of that, but please
confirm.
Second, the same thing may be true, except that it's in one of those
weird hidden DOS box terminals that Windows seems to need to get full
functionality from XEmacs. That you probably wouldn't know about.
To help debug these, try doing C-h f get-buffer-window-list RET, then
if it doesn't show, evaluate
(get-buffer-window-list
(get-buffer "*Help: function `get-buffer-window-list'*") 0 t)
If it does show, we'll need to try something else.
Third, the values of `help-selects-help-window', `pop-up-windows', and
`pop-up-frames' may affect this behavior. Could you try setting them
to different values and see if semi-sane behavior is restored?
