<pre><b>INT 15 - TopView - "USTACK" - SWITCH BACK TO USER'S STACK</b>

	AX = 1025h
Return: stack switched back
Notes:	call only after having switched to internal stack with AX=101Ah
	while TopView requires many API calls to be executed while on the
	  task's private stack, DESQview allows those calls to be executed
	  regardless of the current stack
