Error on Send Mail form

Greetings,

Using CB 1.9 on a J2.5 installation.

On the "Send email" page the label for the send button is missing. The button is there and clicking on it sends the email, but the button label is not visible.

Here's the code for the button:

<input type="submit" class="button" value="Send Email" />

Any suggestions?

Thanks,

Dave
