There does not appear to be a way to disable autoscroll. When dragging an item into a spreadsheet or text Table (or other document I am sure) the frame scrolls in an attempt to match the mouse motion- and very frequently overcompensates.
Calc is used as an example because there is a kluge to obtain the desired behavior. Again, why 'Freeze Window' does not actually freeze the columns selected, is beyond me. But if you freeze the columns then by the time you have dragged an item into them the frame has shifted to the right (after all, the mouse points just off the column boundary) and you have to bring the mouse over to the left and compensate for the overcompensation.
If you have selected columns to be the frozen window are , and then place a file-manager window overlapping the right-most cells of the frozen area, you actually have a frozen set of cells which will not move in response to the presence of a mouseOver.
This is today's kluge but in my mind the desired behavior if an area of the window is 'Frozen' is to make it immutable unless a scrolling action is selected with focus - it should not put you on the Gladiators' Tilt Table just to enter your data item.
Thanks for interesting idea
Option "Disable autoscroll" may help in increasing performance.
If we disable autoscroll, then we can still scroll using mouse wheel for vertical scroll and Shift-mouse wheel for horizontal. And no unexpected scrollings. And we safely can arrange objects near edge of screen.
In 3.5.2 can not find such setting.
Option will be useful in other modules of office too.
