Windows can't be docked in more than one side when keypad is visible

[Former user]

Originally reported on Google Code with ID 338 ``` When more than one windows like mathbook,constants etc. are viewed;these can't be docked simultaneously in more than one side of the main window. These can only be docked in one side. Also, the program does not remember the position of the docked windows i.e. whether windows were previously docked in left side or the right side. The program always with the windows docked in the right side.

Version is 0.10.1

Hope these issues are fixed. ```
