I'm trying to add a line to a RichText box using the .SelRTF property. I've gotton foreground color (\cf#) to work, but I can't seem to make background color (\cb#) to work at all. No matter what I try, the backgroud color of the text added just stays white. Here's the RTF string I'm adding:

rtbDisplay.SelRTF = "{\rtf1\ansi" + ;
"\deff0\deftab720" + ;
"{\fonttbl{\f0\fmodern Fixedsys;}}" + ;
"{\colortbl\red0\green0\blue255;\red0\green127\blue0;}" + ;
"\cf0\cb1 This is a test\'0D\'0A" + ;
"}"

It seems to completely ignore the \cb1. And if I use rtbDisplay.SaveFile "c:\temp\temp.rtf", the \cb gets striped out completely. HELP!!! :)
