8.5 Audio Suite not opening

We've just done an upgrade from 8.3 to 8.5 media composer, and find that although the audio suite is there, when you click on the tools within any of the items, there's no adjustment window? Normally you click on the icon and a separate window opens with all the adjustables within that plugin. Does this show somewhere else now, or did we miss something on the install? (windows 7 OS)

thanks
