CLOCK should work now. Very nice app! It's using a non-supported mapping mode, but apparently that doesn't hurt.

btw, there is a bug in the FASM windows includes which confused hx and caused the GPFs: in FASM, there is

CW_USEDEFAULT equ 8000h

OTOH, the MS platform SDK defines it as

#define CW_USEDEFAULT 0x80000000

apparently, windows accepts the 8000h as well (as does hx now), but it is not documented.

--------------------------------------

about the mouse problem: this almost certainly is due to the mouse event proc not being reset. dkrnl32 uses raw DPMI functions to set the mouse event proc, which has the advantage that it works with any DPMI host, but has the disadvantage that the host cannot clear the event proc on its own if an unhandled exception occurs and the host is terminated the hard way ("terminate s/erver").

--------------------------------------

P.S: and please, don't write "GPF's", write "GPFs" instead! Our admin is very sensible and such things do hurt him physically. :crying:
