Corel 6 floating dockers using Win 7 always open expanded. Need to keep them minimized. See below

I am using Corel 6 with Windows 7.  I use floating dockers all the time.  When I maximize CorelDraw (from being minimized) floating dockers are always expanded even if they are minimized.  This just started to happen recently.  Any way I can change a setting so floating dockers will stay minimized until I want to use them? Thanks. Jon
