Well first make sure they are doing ctrl-b and not ctrl-shift-b. Which is what I was trying when I first read your post thinking it had to be upper case b.
We will leave the post here and if you want it moved just ask and one of us moderators can try another forum. I cannot think of anything in baan to activate this and I am not sure if something on the client might be set to prevent it from sending the ctrl-b.
My latest mantra - make sure you have latest stpapi patches and the latest session object. If on LN then please explore the option of using DAL2 functionality.
