Release Date:   August  28, 1997

Revision:       Version 1.3.5 , 6555X
Release Date:   July 18, 1997
=======================================================================

	1. Completed bug fix #410. The change described below actually
	fixed the problem / area beneath the cursor when cursor was
	forced to SW. However, when the cursor was dinamically changed
	from HW to SW (such as NTSC or interlaced modes), the cursor
	problem still exists. This fix is taking care of it.
	WGA.ASM - ResetHiResMode.
	2. Fixed forced hardware/software cursor support with video
        BIOSs that return function 5F50h with DL[4] = 0 , drivers
        check for panning bit. CURSOR.ASM , CC_CHANGEDISPLAY.  

=======================================================================
Revision:       Version 1.3.4 , 6555X
Release Date:   July 02, 1997
=======================================================================


     1. Bug fix #482 : 65555X , after booting windows from DOS with POPUP
        enabled , cursor disappears. The cause was the POPUP 55X cursor
        initialization code was not being called , instead 655545/548
        POPUP cursor intailization code was called.   

     2.	Bug fix #410 : Alt Tab in/from DOS FS corrupts area beneath the 
	cursor when SW cursor modes (65555 and intermitent).
	WGA.ASM - In ResetHiResMode skip checking HW popup cursor and HW 
	cursor in offscreen memory for SW cursor. The bug occured because
	the above code was redrawing the SW cursor when it was not needed.
	The area beneath the cursor was beeing messed up by the EraseTail_10
	algorithm in that particular instance. ResetHiResMode is called
	when returining from DOS FS and is asyncronuous with the displayed
	screen. Sometimes, the EraseTail_10 (whithin DrawCursor) would not 
	restore the proper save_screen for the SW cursor.


=======================================================================

	switch FS<-> DOS box - Alt-Enter. The screen does not come back 
	until the dir/s is finished.
	WORK31.ASM - InstallBIOS5f51 does use both VMM schedule_Global
	and Call_when_VM_returns based upon PIF bits.
