I runned exkeys in fullscreen.
In Control Panel/Keyboard:
"Standard 101/102-Key ou Microsoft Natural PS/2 Keyboard"
In Control Panel/System:
"Microsoft Windows 2000
5.00.2195
Service Pack 4"
gcc -v says:
"blah blah blah...
gcc version 3.4.2 (mingw-special)"
I'm using Allegro 4.2.0 release version (i will test a 4.3 SVN later).
Some minutes ago, I changed the "GFX_AUTODETECT" to
"GFX_AUTODETECT_WINDOWED" in exkeys.c and recompiled it. When i runned
in windowed mode the problem still was there, nothing changed.
Surely this is a bug inside allegro or inside some Windows API.
PS: Back to 2001, i was programming in VB on those days. I've got some
weird behavior with alt and control keys, but i can't remember exactly
what. Maybe something wrong inside Windows API or Windows keyb drivers.

victor,
which OS, allegro version, compiler, etc..
? fullscreen or windowed and the driver (as listed on the top of
exkeys
when you run it)
? keyb driver.. in device manager, under Keyboards.. mine says
"Standard 101/102-Key or MS Natural PS/2 Keyb"
? in accessability options (control panel), keyb tab.. are any of
those ticked ?
i tried /examples/exkeys in fullscreen mode (DirectInput driver) on
WinXPsp1 msvc7 built...
and my standard 101 keyb's Alt-GR did NOT show any control key
weirdness.

I confirmed that. In exkeys, when i pressed the ALT GR key, the
Left
control got a keypress too. This could stuck the Esc key too.
I'm in Windows 2000 with a ABNT2 brazilian keyboard.

I just tried exkeys.exe (only under Windows 2000) and at first,
the
problem does not appear. However, on closer inspection of the
code,
the
bit where it tests the key_shifts variable is immediately preceded
by
a
ureadkey(NULL); I tried adding readkey(NULL) to my example
program,
and although it now stops and waits for a regular key (letter,
number,
etc) to be pressed before reading key_shifts, when I press a
regular
key, the key_shifts variable is updated with the correct state of
the
shift-keys. From this, I conclude that the windows version only
updates
key_shifts when a regular key is pressed, but the DOS version
keeps
key_shifts in sync with the state of the keyboard. If exkeys.exe
had
a
portion where it just displayed the key_shifts variable without
waiting
for readkey(), then the problem will be demonstrated.
A manifestation of the problem where ESC does not work when the
CTRL/ALT keys are 'stuck' in exkeys.exe is where I cannot press
ESC
to
continue unless I press some other key first.
Also, in exkeys, when I press ALT-GR, in the table of keys on the
right
of the screen, it says I've pressed both ALT-GR and CTRL when I've
not
pressed CTRL. If CTRL is held down, the values for both ALT-GR and
CTRL
are correct. However, if I hold down RCONTROL when I'm holding
down
ALT-GR, then the indicator for CTRL becomes un-set, although if
I'm
holding down all 3 keys at once, the indicators are at their
correct
values. None of this happens with the regular ALT key.
I have a UK keyboard. According to the Windows Input-locales
section
of
the regional options applet, the input-language is "English
(United
Kingdom)", and the Keyboard layout / IME is "United Kingdom".
BTW. I added the following lines inside the main loop of my test
program
if(keyboard_needs_poll())
{
poll_keyboard();
}
and the results are still the same - even if I get rid of the if
and
just call poll_keyboard()
