I have a richtextbox wrapped in a user control and in a tab control on a page (user control)

Text from the control (.richtext method) is saved to a database table using a wcf service

Text is set into the control using .richTextBox.RichText = info from database 

I use the new clear function before I set in text from a new database row

Occasionaly line feeds are ignored and the text all appears, overlapping, on the first line.  

This happens every second time if I

clear

set text

show another page altogether

return to the same page (cached in memory as I can't find a way to remove it from memory)

clear

set the same text from the same row (ie identical text - this time it now appears one one line)

If I add the one line below it only happens once in awhile

clear

set text

>>> clear richtextbox before showing next page

show another page altogether

return to the same page (cached in memory as I can't find a way to remove it from memory)

clear

set the same text from the same row (ie identical text - once in a while text shows up on first line)

Any suggestions will be appreciated.
