Our 32bit builds have problems to generate more sheets and crash with a
std::bad_alloc

Increase this limit again as soon as we can handle std::bad_alloc

Otherwise it gets confused with normal arrow objects during re-
positioning.

Inserting a new sheet would not update the anchored sheet index. Fixed.

If not, cell-anchored objects would get stuck on the old sheet
position, which is not good.

This prevents drawing objects from disappearing on file reload.

The delay was a good idea, just the 1s was too long.
