	the problem comes from the fact the the "PAUSE" key on your keyboard

	sends the following codes:
	"<CONTROL on><NUMLOCK on><NUMLOCK off><CONTROL off>"

	the keyboard mapping program translates this (under your
	mapping) to:
	"<CAP LOCK on><NUMLOCK on><NUMLOCK off><CAP LOCK off>"

	a sequence which has the net effect of toggling 
	both NUMLOCK and CAPLOCK keyboard states...

	seems your best workaround is to use "control -S" or
	"control-NUMLOCK" manually...

	the workaround I used was to disassemble the keyboard, and
	cut and jumper the traces for CONTROL and CAPLOCK keys

	(who needs a warranty?)
