The window "Table tools" takes place not on the screen

Hello. Excuse me for a very bad English. I am writing this letter through a translator.
I want to report a problem with the program.
When you enter the "Maintenance", the window "Table tools" takes place not on the screen. Therefore it is necessary to press the button "Expand the window". After work, the window is closed. If you then open the window, it again turns not on the entire screen and moves to the right. You can make the window remembered his last position, and set to full screen?
