Custom Layout - Excess Windows

[Christopher]

I have created a customized Softimage Layout, and within that new layout I have a collapsible menu.  When a another program window is open, overlapping the Softimage window, and I either minimize or close the other window (not the Softimage window) it leaves some of it within the collapsed menu in Softimage.  What you are looking at in the image is a collapsed menu, another program window was open on-top of the Softimage window, I then closed that window, what is left behind is some of the other program window within the collapsed menu in Softimage.  I have updated my graphics card driver but the problem does not go away :(
