using mouse to select cells in calc is uncontrolled

When I try to use the shift left mouse button to select a block of cells in calc the curser flies off to the right until I move it outside the left edge of the window, but it still does not return to the general vicinity of the first cell. I have to abandon the mouse and use arrow keys to make the selection since the last update to 6.0.7.3. This was not a problem in the previous release.

Is there any other work-around than using the arrow keys?
