Manual Eratta:
===============================================================
The following properties do not appear in the manual. You can
refer to the documentation in the help file for these properties.
-----------------------------------------------------------------

              Mh3dList)

YDivisions - (MhHistograph)

AllowBlank - (MhDateInput)

LoadComplete - event (MhFileDisplay)

LoadStart - event (MhFileDisplay)

TextExtent - (MhTree)

MhDateInput and 2 digit years
-----------------------------
Because of the increased range of years with this control, if you 
use 2 digit years, we must make some adjustments. Two digit years
can cover only a 100 year range. When you first change to a two 
digit year the MinYear will be set to the current Year - 65 and 
MaxYear will be set to the current year + 34. You may change this 
range, but it must cover only 100 years when using 2 digit years.

This could cause a problem if you switch between four and two digit 
years. When switching back to four digit years, the MinYear and 
MaxYear are not adjusted and will continue to have this 100 year 
range, unless you change it.

===============================================================
Mh3dCalendar and 2 digit years
-----------------------------
Added MinYear and MaxYear properties. See the manual / help file
for documentation.

Because of the increased range of years with this control, if you 
use 2 digit years (this includes binding to an access date field) 
we must make some adjustments. Two digit years can cover only 
a 100 year range. When you first change to a two digit year the 
MinYear will be set to the current Year - 65 and MaxYear will be 
set to the current year + 34. You may change this range, but it 
must cover only 100 years when using 2 digit years, or when binding 
to an Access date field.  Note that you can save the dates in 4 
digit years by binding the calendar to a regular text field in an
Access database.

This could cause a problem if you switch between four and two digit 
years. When switching back to four digit years, the MinYear and 
MaxYear are not adjusted and will continue to have this 100 year 
range, unless you change it.
===============================================================


===============================================================
MhTab and standard option buttons.
----------------------------------
MhTab controls the TabStop property in order to keep "off
screen" controls from receiving the focus when using the Tab key
to move from control to control within a particular folder.
When the control's folder is not active the control's TabStop is
set to False. 

VB's option button has an "anomoly", in that the TabStop
property is changed when the .Value property is set.  Setting
the .Value property of a standard option button while it is
moved off screen will cause the TapStop property to be set to
True and it will be included in the tabbing order and the
control could receive focus while it is not visible.

The Mh3dOption button in VBTools does not exhibit this behavior.
The best solotion is to use Mh3dOption buttons rather than VB's
option button.
===============================================================

Discontinued Controls-
---------------------
The following controls from version 3 were discontinued (not
carried forward to version 4).  All of these controls have 
either been replaced in functionality by controls in Visual Basic
itself, from 3-D Gizmos, or with new controls.  If you have
VBTools version 3, you can still use this controls and we will
support these controls until the next release of VBTools.
The only caveat is those that use the runtime DLL (MHRUN300.DLL) 
will still require that this DLL be distributed with them.

MhFlip
MhLine
MhMDI
MhPicture
MhSpin
MhSpread
MhChart
MhGauge (use 3-d one)
MhHsb
MhIconTag
MhState (use 3-d one)
MhTag
MhVsb


Interface Designer (FPGRID10.VBX)
=================================
The Interface designer was not included with the original release of VBTools 
and as such does not appear in the manual.  It does appear in the current help
file and you can refer to GRID.HLP provided with this product.


===============================================================
MhTab - slow redraws
--------------------
It is natural to have some slow redrawing when dealing with large numbers of
controls on the MhTab control.  The best way we have found to speed up the 
drawing of these controls is to place a frame control on each page of the 
MhTab control and draw your controls on the frame.  If you already have an MhTab
loaded with controls, simply cut them from the form as a group, draw the frame 
on the MhTab and paste the group of controls into the frame.  This speeds up
MhTab drawing because it only has to handle the frame.
