Possible bug? Rated 5 out of 5 stars

I'm facing an issue where as long as the Sidebar is open (as in, not hidden) i can't Write a new email.
not by right clicking a contact and selecting to "Compose Email To" and not by clicking on the "Write" button.
Closing the Sidebar resolves the issue...

any ideas?
