Hi all. 

For some reason my tool table and my offset table wont display.  I click it and it shows is displayed down on the tool bar but i cant get it to display.  even when i roll over it, it shows it as a blank page.   THis is the first ive seen of this

Most likely the window is positioned by the developer to display on another screen in a dual screen system.
