Windows Live Mail 2012, backspace (to delete text) is choppy

About a week ago, I noticed that something had changed in my Windows Live Mail 2012.   

When I create a new email and type in the text box, if I need to use backspace to delete any text (typos), it is choppy.  It is like a stutter as it moves backwards and lags.  

This is the  only program that does this.  Backspace is fine when using Chrome (tested it out on the search box.  I typed some text then used backspace to erase it).   Backspace to delete is working fine inside this text box (the one I am typing in now) as well.   Word is normal as well.  It's only in the new mail windows text box.

Any ideas??  It was working just fine before this started so it's a new problem.

Thanks!
