Sun Jul 28 17:57:19 1996  Alexandre Julliard  <julliard@lrc.epfl.ch>

	* [loader/task.c] [include/task.h]
	Implemented SwitchStackTo()/SwitchStackBack().

	* [include/wintypes.h] [loader/main.c]
	Added __winelib variable to distinguish between emulator and
 	library at run-time. Later on, this should avoid some
 	recompilations when building Winelib.

	* [windows/property.c]
	Implemented Win32 functions for window properties.

Fri Jul 26 18:00:00 1996  Alex Korobka <alex@phm30.pharm.sunysb.edu>

	* [controls/listbox.c]
	Implemented LBS_SORT style, WM_COMPAREITEM, and WM_DELETEITEM
	messages.

	* [controls/menu.c]
	Call TranslateMessage() to enable shortcuts (on WM_CHAR).

	* [include/cursoricon.h]
	Moved #pragma pack(1) back to where it belongs.

	* [objects/palette.c]
	RealizeDefaultPalette() maps to system colors only.
	Do not broadcast palette notifications when in TrueColor.

	* [objects/color.c] [include/palette.h]
	Miscellaneous optimizations. Had to fix several
	"improvements" made to my patch for previous release.

	* [objects/dib.c]
	Reverse dib bits order for 24-bit SetDIBits().

	* [objects/dc.c]
	GetDeviceCaps() does not return RC_PALETTE when in TrueColor.

	* [windows/scroll.c]
	Scroll update region too.

	* [windows/message.c]
	Include QS_MOUSE into the event mask for nonclient mouse
	message filter. Fixes problems with Word 6 freezing when
	mouse hits nonclient area.

	* [windows/win.c] 
	Allow top-level windows to be linked as HWND_TOP in CreateWindow().

	* [windows/winpos.c] [windows/mdi.c]
	Attempt to fix control menu duplication.

Fri Jul 26 09:49:35 1996  Marcus Meissner <msmeissn@cip.informatik.uni-erlangen.de>

	* [files/drive.c]
	GetDriveType32A(): return value for CDROM fixed.

	* [files/file.c]
	SearchPath* added.

	* [if1632/gdi32.spec] [objects/brush.c]
	SetBrushOrgEx() added.

	* [loader/pe_resource.c]
	If even loading the default entry fails, we just use the first
	entry from the resource directory.

	[loader/task.c]
	SetSigHandler() stub added, Paradox 4.5 now starts up.

	* [misc/comm.c] [include/windows.h] [if1632/kernel32.spec]
	COMM functions updated to win32, not complete.

	* [misc/lstr.c]
	FormatMessageA partially implemented.

	* [include/miscemu.h] [memory/selector.c]
	  [memory/global.c] [miscemu/dosmem.c]
	DOS memory handling changed: 1MB preallocated block, real-mode
	segment handling possible, SetSelectorBase into lower physical 1MB
	possible.

	* [miscemu/dpmi.c]
	Real-mode segments changed, real-mode int 21,ax=6506 added.
	AX=0x0303 added.

	* [multimedia/time.c]
	Fixed bug in killTimer.

	* [objects/bitmap.c]
	LoadImageA partially implemented.

Wed Jul 24 18:20:24 1996  Albrecht Kleine  <kleine@ak.sax.de>

	* [include/dde_mem.h][include/dde_proc.h]
	  [ipc/dde_atom.c][ipc/dde_proc.c][windows/message.c]
	  [ipc/generic_hash.h][library/miscstubs.c]
	Changes for error free compilation using "--with-ipc":
	replaced some names with *16-equivalent (e.g. MSG to MSG16),
	modified prototype of function DDE_GlobalFree() .

	* [objects/palette.c]
	Added check for metafile-DC in GDISelectPalette(),
	GDIRealizePalette(),RealizeDefaultPalette() and
	IsDCCurrentPalette().

Tue Jul 23 22:46:53 1996  Andrew Lewycky <plewycky@oise.utoronto.ca>

	* [controls/edit.c]
	EDIT_WM_Create: Don't EDIT_EM_ReplaceSel if created with lParam = "",
	fixes Winhelp.
