I am unable to send out an email by typing in the Category name.

Also the + plus sign to expand the email list inside the TO: box does not work.

Help!

Update:  I found some advice to Sign Out of my Windows Live Mail account, and then Sign In again (which required my email password).  This appears to have restored by Category mailing function. 

> What would be nice to know is why Signing Out and Signing In clears this.  Maybe the Help Desk could elaborate.
