Hey Clives,
My welcome to PCHF as well, I am so sorry that it has taken us so long to get to your thread. Is this something that just suddenly occurred? Are you using Word as your email editor?
Several things come to mind some banal, and some not so much. First, I would check to see that your default font color has not somehow been switched to white, either in Outlook, or in your Normal.dot template.
Second, I would try an Office Repair, to do so, close all office programs, install the CD, and ask for a Repair Install.
Thirdly, I would check for malware, it is quite possible that something malicious is deleting your text. If the previous attempts do not get results, please follow the instructions in PreWork found in my signature, and post back with the resulting logs.
Looking forward to your reply,
TTFN
LGW
