very strange rtb operation

[vbcandies]

I am trying to write a routine that wll append new text to an rtb:

AppendRTB(theText, theColor) which will just ad to the text already present & also color the new text as desired (not touching anything from earlier).

I thought I had it working, then noticed that in cases when my text had a cr lf in it, I GET a totally skipped line (eg: a blank line appears from nowhere in between)
instead of:

hello how are you
mr jellyfish

---get-----
hello how are you
<<<----blank line
mr jellyfish

=====================
if I do something like rtbmsg.text = rtbmsg.text & newtext the appending is proper, but all colorization is lost. I searched and found this strips out some hidden formatting provision.

IF I DO rtbmsg.seltext = rtbmsg.seltext & newtext (as I was doing in my program) by itself it appends properly!!!! however no color is being set by this single line

In order to set the color, my understanding is you need to select the start position & length of text to colorize.

JUST BY ADDING THE FOLLOWING single code LINE I GO BACK TO THE IMPROPER APPENDING!!!

oldlen =len(rtbmsg)
rtbmsg.seltext = rtbmsg.seltext & newtext
rtbmsg.selstart=oldlen '<===causes blankl line skipping !!!!!

Why would simply setting up a start position, suddenly cause this extra line skipping to happen?!!!??? does this modiy the the text at all?? It should just mark a position!! I can (and have) add a few more lines of code to change the color as desired, but I do not want the line skipping
