I had been building the new version using MinGW, but I just
reinstalled it
from Rob's PPM. This installed the new documentation correctly and I
now see
that there is some Timer documentation.
Apologies for flooding the list with replies to myself...

I spent a little time to dig into this more. As I suspected, this isn't a
bug, but a change in implementation. Under version 1.01_01, the Kill()
method simply made a call to the system function KillTimer. Version
1.02_02
explicitly destroys the timer, which includes removing its definition
from
the window hash. Hence, my "nothing strange" code below was defining each
timer then destroying it in the next step!
In practice, there was a more subtle difference. The effect of the old
Kill() method was simply to disable the timer; it could then be
resurrected
with a new Interval(). I'm not sure that this behaviour was correct or
desired, but I was using it in my program. I can't just remember why I
did
it that way, but it was probably a "safe" way of ensuring the timer
didn't
fire until I was ready for it (the alternative being either to make the
Interval() very large--for some arbitrary value of "very large"--or to
repeatedly kill and redefine the timer). It could also have been to
cover a
deeper problem in the implementation, but time will tell.
The Win32::GUI documentation for Timers is bare, but the MSDN
documentation
does suggest that the new behaviour is correct. However, version 1.02_02
will break any program using the old behaviour. The addition of a simple
definition to the method documentation would help.

Sorry for the delay, but it's been hectic at work this week.
I've attached (an image of) the error message. Sure enough, a 'dump'
of the
main window object shows that the timers don't get registered for some
reason:
bless({
# tied Win32::GUI::Window
"-accel" => 41_681_429,
"-font" => -334_885_755,
"-handle" => 2_032_212,
"-minheight" => 595,
"-minwidth" => 850,
"-name" => "mw",
"-timers" => {},
"-type" => 0,
etc.
There's nothing strange about the declaration of the timers:
$mw->AddTimer("tmList",100000);
$mw->tmList->Kill();
$mw->AddTimer("tmLoop",100000);
$mw->tmLoop->Kill();
etc.
The same script runs with no problem on 1.01_01. There, the dump shows:
bless({
# tied Win32::GUI::Window
"-accel" => 25_036_785,
"-font" => "-1626733967",
"-handle" => 6_358_280,
"-minheight" => 595,
"-minwidth" => 850,
"-name" => "mw",
"-timers" => {
1 => "tmList",
2 => "tmLoop",
3 => "tmStatus",
4 => "tmYearVerify",
5 => "tmTrackVerify",
6 => "tmGenreVerify",
},
"-type" => 0,
etc.
I'll keep trying to narrow it down and will post back if I do.

hit another more worrying problem: I have a large-ish program, which
uses a number of timers. With 1.02_02 I get an error whenever any one
of the timers tries to fire (Can't locate auto/tmList.al in @INC...).
I tried to replicate this in a smaller program, but was unable to; a
simple program with a timer works fine. It's quite possible that my
program has a flaw, of which 1.01_01 is more tolerant, but there may
be a problem in the new GUI code.
That is indeed worrying. There have been some minor changes to the
timer code that Reini made when he put his tests together, but I
can't immediately see anything that would cause this.
Typically when I see errors like that it turns out to be a
mis-spelled method call or window name, but if that was the case I
would expect it to fail in 1.01_01 too.
If you can't get a short example to exhibit this problem, can you
post the exact error message that you're getting.
Rob.
