I've now tried it on Windows 98. Here are the results.



OS: Windows 98 SE
Allegro: 4.2.0 compiled with MSVC 6 (built using the Direct X 8 SDK)
Direct X: 8.1 (4.08.01.0881)
Keyboard driver: Standard 101/102-Key or Microsoft Natrual PS/2 Keyboard
Keyboard properties: Language: En English (british)   Layout: British

exkeys keyboard driver: Driver: DirectInput keyboard

Fullscreen+Windowed: Like in Windows 2000, pressing CTRL, releasing CTRL 
and then pressing ESC does not register the press of the ESC key. Also 
like in Windows 2000, the indicator for CTRL remains unlit while the 
control key is stuck, but pressing a regular key un-sticks it. Also like 
in Windows 2000, pressing CTRL and ESC together bring up the startmenu 
and make the app lose focus.

Fullscreen+Windowed: ALT-GR behhaves normally.

Sometimes if I switch out using CTRL+ESC and switch back in again, the 
message "readkey() returned 15104 (0x3B00)" scrolls continuously. This 
happens in both Windowed and fullscreen modes.

Fullscreen: If I press ALT-TAB, the app switches out, but when I switch 
back in, sometimes, TAB is shown as continuously pressed and the message 
"readkey() returned 16384 (0x4000)" scrolls repeatedly. I've not managed 
to reproduce this in windowed mode.



BTW: Some info on my Windows 2000 setup I didn't include in my last mail...

Windows 2000: DirectX 9.0c (4.90.0000.0904)
Windows 2000: Allegro was built using the SDK for Direct X 8

Also, in both Windows98 and Windows2000, I created an EXE that uses the 
Allegro DLL (ie. not staticlinked).



I've also tried this under DOS.


Dos: (dos running under Win98)
Allegro: 4.2.0 compiled with DJGPP

Here are some findings:

exkeys keyboard driver: PC Keyboard (DOS)

ALT-GR behhaves normally.

The CTRL key does not get stuck, and pressing escape immediately after 
CTRL works fine.

CTRL-ESC, ALT-ESC and ALT-SPACE trapped by windows and cause app to 
switch out. Of those 3, only ALT-ESC causes a key to be stuck (the ALT key).

However, if I switch the DOS-app out and then switch back in (releasing 
the keys when switched out), the key-indicators on the right of the 
screen are not un-lit on the switch-in, but it appears that the program 
behaves as if the keys are not pressed (no continuously scrolling 
messages, and ESC behaves normally if the indicator for ALT is lit).


I also tried running the same DOS exe in DOS without windows. The 
results were the same as the DOS version, except that the CTRL-ESC, 
ALT-ESC and ALT-SPACE did not switch the app out (they behaved as 
expected and lit the correct indicators).


Anyway, I'll try and get round to trying the changes that Elias suggested.
