Titlecase lost during Send Mail script

[John Fowler]

When sending confirmation emails to customers, I apply Titlecase to the leftmost word in the name field, resulting (previously) in a standard-formatted first name, regardless how it was entered in my shopping cart. But about 2 weeks ago, even though I made no changes at all to my Send Mail script, Titlecase just stopped working, leaving greetings like, "Hey CHARLES" and "Dear earl". I've tried it both as a Calculated field, as well as just using the calculation option in the body text of Send Mail. As a field, it shows up properly Titlecased, but when it exports to an email, it's back in its bad formatting. The weird part is, it worked just fine for several months before doing this.

Here's the offending part of the formula:

TextStyleAdd (LeftWords( Sales::Name ; 1 ) ; Titlecase)

Any suggestions are welcome.
