reports on sidebar

[fideli]

Hey everyone, 
 
This is a serious n00b question, but I've searched all over the menus and 
documentation.  I was screwin around with my gnucash file, and I added some 
"reports" to the left sidebar, most of which are not really needed right now.  
Then, after the fun was over, I was horrified to note that I could not delete 
these reports.  I tried right-clicking them, I tried Del, Ctrl+Del, Options 
menu, preferences menu, etc., but I could not delete them.  Does anyone have 
any idea how to delete reports from the left sidebar?  Thanks in advance.
