keyboard production setting (long standing bug)

[Steven S. Dick]

I complained about this bug a long time ago, but was not able to
explain exactly how to reproduce it, and it didn't get fixed.

I think I have narrowed it down some.

If you use the mouse to tell a mover where to go, and then immediately
after use the keyboard (P) to tell a producer to build, between choosing
what to build (mouse or keyboard) and telling it where to build, the
display is scrolled an amount equal to how much the mover was moved.
(The map is scrolled back after the production location is choosen.)

If, however, before building, the map is recentered, the map is not
scrolled at all.

This occurs in survey mode, but not as reliably.
I haven't completely figured out how to trigger this bug there.
