[imp] disabling the sidebar

[Liam Hoekenga]

When I got to...

https://localhost/horde/imp/

I get the "Welcome to Mail" banner.  When I log in,

and log in, I get passed through login.php, my URL looks like...

https://localhost/horde/login.php? 
url=%2Fhorde%2Fimp%2Fmailbox.php%3Fmailbox%3DINBOX%26amp%3BHorde%3Db72a8 
c647d341230f94b86650e00cfbf&Horde=b72a8c647d341230f94b86650e00cfbf

and I get the sidebar.  If I then go back to  
https://localhost/horde/imp/, I get IMP w/o the sidebar, like in the  
3.x release... which is what I want.

Is there any way to disable the horde sidebar?
