SYMPTOMS

When using a dithered color (other RGB color pairs may also exhibit the same
behavior) as a background color in a text box, edit region, grid, or check box
(other controls may exhibit the same behavior), you see only the solid side of
the RGB color pair as your background color.

STATUS
======

Microsoft has confirmed this to be a problem in the Microsoft products listed at
the beginning of this article. This problem has been fixed in Visual FoxPro 5.0.

Steps to Reproduce Problem
--------------------------

Create a program containing the following code and run it:

    PUBLIC myform
     myform = CREATEOBJECT('form')
     myform.ADDOBJECT("mytext", "textbox")
     WITH myform.mytext
       .LEFT = 15
       .TOP = 6
       .VISIBLE = .T.
       .BACKCOLOR = rgb(128,255,255)  && Should change the back color to a
       ** light blue
     ENDWITH
     myform.ADDOBJECT("mycheckbox", "checkbox")
     WITH myform.mycheckbox
       .LEFT = 15
       .TOP = 50
       .VISIBLE = .T.
       .CAPTION = "Check 1"
       .BACKCOLOR = RGB(128,255,255) && Should change the back color to a
       ** light blue
     ENDWITH
     myform.ADDOBJECT("myedit", "editbox")
     WITH myform.myedit
       .LEFT = 200
       .TOP = 40
       .VISIBLE = .T.
       .BACKCOLOR = rgb(128,255,255) && Should change the back color to a
       ** light blue
     ENDWITH
     myform.ADDOBJECT("mylabel", "label")
     WITH myform.mylabel
       .LEFT = 200
       .TOP = 6
       .VISIBLE = .T.
       .BACKCOLOR = rgb(128,255,255) && Should change the back color to a
       **light blue
     ENDWITH
     myform.SHOW

The solid side of your RGB color pair may vary due to your video driver. To see
what the solid and color side of your RGB color pair is, go to the Control Panel
in Windows, and double-click the Colors icon. Click the Color Palette button,
and then click the Define Custom Color button. Then enter 128 for Red, 255 for
Green, and 255 for Red. You will see that the Color side of RGB(128,255,255) is
a light blue but the solid side is Gray, White, or Blue Gray depending on your
video driver. (You can also use the Custom Color Palette in Visual FoxPro to do
this.)
