A problem in SDL prior to version 1.2.14 was causing the behaviour of the LOCK key to not work as it should have. Instead of returning the up/down key status it was returning the toggled state and so caused problems with games that used it.
The current workaround is to issue the command:
set SDL_DISABLE_LOCK_KEYS=1
every time before launching DOSBox.
I don't know what version of SDL is included with DOSBox 0.74 but 1.2.14 is available from http://www.libsdl.org/release/SDL-1.2.14-win32.zip if the one included with 0.74 is obsolete.
Apparently the necessary setting of the SDL_DISABLE_LOCK_KEYS can be done internally by the emulator. Could that please be done for V0.75 so that the users don't have to stuff around with environment variables?
