	Move functions GetWindowTask(), GetNumTask(), EnumTaskWindows()
		from 'loader/library.c'.

	* [if1632/user.c] [if1632/kernel.c]
	Put Atoms functions entries.

	* [controls/combo.c]
	New functions DirDlgSelectComboBox() & DirDlgListComboBox().

	Tiling of child windows.

Mon Apr 11 20:48:28 1994  Alexandre Julliard  (julliard@lamisun.epfl.ch)

	* [windows/winpos.c]
	Revert focus and activation to previous window when hiding a window.

	* [windows/syscolor.c]

	Nothing much more than a stub for LoadModule(), I saw there a lot
		to be done in that corner, I will come back later ...

	* [loader/library.c]
	New functions GetWindowTask(), GetNumTask(), EnumTaskWindows() 
			and associated modules & tasks linked-lists.
	(it's only an 'emerging bud', more to come next weeks).

	* [loader/wine.c]
	Use LoadLibrary() instead of LoadImage() for 'sysres.dll'.

	* [control/menu.c]
	You can now click outside menu region without problem.
	Keyboard navig more smootly, even if a child has the focus.
	Bug fix in InsertItem(), (bad linklist when insert point not found).
	change Realloc for Free & Alloc in ModifyItem().
	MF_STRING now set BLACK_PEN to fix bug of bad color of the underscores 
		done by DrawText(), (maybe it should done in DrawText() itself ?).

Sun Apr 10 14:06:08 1994  Erik Bos (erik@trashcan.hacktic.nl)

	* [misc/profile.c]
	.INI files will now be stored in / loaded from the windows dir
	if no path is supplied.

	* [if1632/kernel.spec]
	Fixed GetDriveType's prototype.

	* [if1632/winsock.spec] [include/winsock.h] [misc/winsocket.c]
	Fixed prototypes: winsock uses a word as socket handle not an int.

	* [misc/winsocket.c]
	Added heap allocation for returned structures.
	Added non-blocking WSAAsyncGetXbyY() functions as blocking ones.

	* [loader/wine.c]
	Added IsDLLLoaded(), used in LoadImage() to prevent loading
	a dll multiple times.
	Directory is added to wine's path when a fullpath is supplied when
	starting wine.
	LoadImage(): DLL filename used instead DLL's own internal name,
	fixes 'Bad DLL name' errors.
